Yo, heads up -- the E71's only half of the story with Nokia's new line of business sidekicks. For those of us who bust out T9 text with aplomb, the E66 might be the better option, especially when you factor in its narrower form factor, arguably (okay, very arguably) nicer look, and an utterly brilliant slide mechanism. Having trouble deciding? Perhaps our little look at the E66 over on Engadget Mobile can be of assistance.

If the pen truly is mightier than the sword, Livescribe's Pulse smartpen ($149 with 1GB of flash memory, $199 with 2GB) may be able to take out a tank at 50 meters. Arguably the most technologically advanced writing instrument not intended for killing a Bond villain, the Pulse includes an infrared camera (for recording text), dual microphones, a speaker, a headphone jack, and an OLED display that can even play back short "movies" (animations synced with sound). And it manages to pack it all in a pen size that, while still a bit thick, is relatively comfortable and thinner than its closest technological ancestor, the now-discontinued Logitech io2.

Using its noise-canceling microphones and ink recognition system, the Pulse can be used to either take written notes that are uploaded to the PC, or record audio. But its greatest advance for note-taking over previous smartpen systems such as the io2 is the ability to synchronize written notes with audio. Simply put the pen into "Paper Replay" mode and tap on some text to hear what was being said as you scribbled. The result is the next best thing to real-time transcription. It can be used to check what may be an unclear or hastily scribbled note, focus on commentary while the pen captures the content, or create or copy a diagram while it is explained via audio.

But first, whatever is being written will have to be done so on paper designed explicitly for the pen. Like previous products that use Anoto technology, the Pulse needs smart "dot paper" to make transcription work. Without a doubt, this requirement will be a deal-killer for many, and limit the Pulse's everyday utility for some time to come. In contrast, simpler products such as the IOGear Mobile Digital Scribe uses ultrasound to track a pen's position and can be used on any paper (and the pens in such systems are smaller as well). To make dot paper more readily accessible, though, Livescribe will offer a template that should allow many customers to print their own dot paper at home. And dot paper enables the Pulse to pull off some pretty slick feats. Read on.

Well, Bill, it's just about quittin' time out here on the left coast, so with your final day at Microsoft drawing to a close, we wanted to present you with a little farewell card. It's not much, but we hope you like it.

Bill,
I can't believe you're already taking off! They even going to let your pension fully vest? Just kidding, I think heard somewhere that you're worth a lot of money or something. Thanks for the Xbox 360 and for always being so damn friendly -- promise I'll try my best to think only of Allchin whenever I bluescreen. Come visit soon and KIT, okay?
Yours Truly, Ryan

Being that it is Bill's special day and all, we figured we'd give you a shot at stepping into his shoes and shaping Microsoft into something even more dominant that the juggernaut it is. Just imagine taking a seat in the biggest corner office Redmond has to offer, getting your Outlook set up, fiddling through a mess of old floppy discs and finally conjuring up a business plan. How in the world would you tweak / overhaul / etc. Microsoft if you were suddenly dubbed the big kahuna? We know this one's wide (and we mean gaping wide) open, so feel free to write a book down there.

Damn, Bill, you have come a LONG way. Look at you there back in '82, you handsome devil. As part of our tribute, let's take a quick look back at the top ten greatest (and not so great) products created on Bill-time, shall we? Don't worry, it'll only sting a little.

Money-losing companies with interesting technology and a small, if rabid, customer base still frequently tend to sell for healthy chunks of change -- especially in the wireless space. We know Helio was burning cash like crazy, but that doesn't entirely explain why SK Telecom was so absurdly desperate to dump their $500m investment. At a $39m acquisition price, SK didn't just lose its shirt -- it lost that, the shoes, and then the pants. You know, the pants with a half-billion dollars in them.

Now, if you look at nothing other than the price per subscriber of some other, larger mobile acquisitions, Helio's numbers seem even crazier. Alltel's subscriber base is going to Verizon for about $2,100 per customer, and back when Nextel sold to Sprint, each sub went then for about $2,350. Helio's $39m sale to Virgin nets them $230 per subscriber. That's now what you're worth to Virgin, Helio subscriber -- $230 on an $80 ARPU. Clearly there's a lot more value in acquiring more than ten million subs than under 200k, but is that value ten fold?

And then to add insult to injury, the piddly $39m Helio did get from Virgin was an all-stock deal, which basically means SK won't be recouping material costs any time soon. Granted, that does amount to 17% of Virgin Mobile USA's market cap, and SK gets two seats on VM's board, but damned if Helio isn't like the reverse-Brewster's Millions of cellphone companies. Basically our pet theory right now is that either SK is playing the Korean tax system for the maximum possible write-off, or they literally didn't have another soul to turn to in this whole wide world. We know Helio wasn't in good shape, but a $39m all-stock deal means they basically stood on the corner and gave the company away to whomever was passing by at the time.

We wanted some more expert opinions, so we hit up a couple of old Engadget pals. Om Malik had this to say: Their losses are huge and there is no hope in sight. Why Virgin bought so few subscribers, I don't get. My best guess is that SK Telecom wants to do something with Virgin. Helio was one giant misexecution -- it is a micropennies on the dollar sale.

Michael Gartenberg offered this: I suspect there were not a whole lot of options... who else would have bought this thing? It's clear the MVNO model doesn't work for the most part. Virgin was probably the only buyer who had interest and it was probably the best chance for Helio's investors to get some of that money back.

Bottom line, it looks like Virgin and its shareholders should be pretty stoked today, because by all accounts they got a pretty killer deal.

As part of our ongoing Bill Gates Day coverage, we present to you the Bill Engadgethology. This is by no means every Gates-related story from over the years -- just the choicest cuts from Club Bill Gates.

We got a look at some engineering prototype versions of Dell's new Studio 17 and Studio 15 laptops, so while they might be lacking a minor bit of polish here or there compared to the real versions, Dell certainly had these up and running a good couple months ago. We're not totally blown away by the design, but it's certainly a step in the right direction for Dell, and a few elements (like the hinge) even seem to be taking some cues from Lenovo's ultra-designed IdeaPad line. There's no denying that the Studio 15, with its flush-to-the-edges keyboard strikes a more stunning figure than the slightly bleh Studio 17 version, but neither one is quite as thin as we'd like, and the material doesn't quite shake off the cheap plastic feel of Dell's Inspiron series. But hey, color (and graphic) lid customization is fun, and you're still going to be hard pressed to beat Dell's prices. Pics are below, and we apologize for the blurring: a few unannounced products snuck into the shots, but hopefully we'll be hearing more about those shortly.

So we dropped by our old friend Peter Rojas's place (you know, the guy who started this site) -- turns out that since he's a music executive and stuff now, he got himself hooked up with a prototype limited edition Joy Division Zune. (Yeah, the irony in that isn't lost on us.) From the absurdly elaborate pivoting, platform-raising box, to the black fabric wrap (which looked blue to our camera), to the faux-LP liner, to Peter Saville's signature etched in foam, they clearly did Joy Division justice on this one. Which they damn well should have, because in case you couldn't already tell, we're all Joy Division fans around these parts -- which means we'd have the music to load this Zune up, being that the only thing it doesn't have is the back-catalog.

[Thanks, Peter!]

We had a chance to play with Research In Motion's upcoming BlackBerry Bold handset tonight, and we came away happily impressed. To start things off, the keyboard felt easy enough to use, at least easier than the 8830 we're often forced to use for work email. Gone are the sharp protrusions, replaced with a nice flat surface upon which to click.

Of note was the Bold's user interface. Menus are clean and easy to read (despite some strange icon choices, see below), and response time is about as quick as one could hope, especially compared to other phones out there that seem to struggle with their operating systems.

We spent some touching (get it?) minutes with the new LG Dare that's hitting Verizon Wireless today, and while we didn't come away from the experience a changed human being, we've gotta congratulate LG and Verizon for the obvious effort they've put into this unit. Particularly with the hardware the phone seems determined to differentiate itself from its iPhone competition, with helpful tactile feedback while typing, (almost helpful) handwriting recognition, video recording (in slow-mo, if you'd like) and even editing, and the beefed-up photo taking capabilities that a 3.2 megapixel sensor and built-in flash provide. The basics aren't too bad either, with a sturdy and bright screen, peppy EV-DO Rev A., expandable memory and a flush 3.5mm headphone jack.

Are we taking a shot of the 8.1 megapixel Sony Ericsson C905 here, or is it taking a shot of us? Find out the answers to these burning questions and much, much more as we take a quick peek at the C905 alongside the Z780 and the mighty XPERIA X1 over on Engadget Mobile!

Ariel Waldman contributes Movie Gadget Friday, where she highlights the lovable and lame gadgets from the world of cinema.

Last month on Movie Gadget Friday we reviewed the rough and rugged modified gadgets of the post-apocalyptic era in The Road Warrior. Shifting from stick shifts to spaceships, this week examines the pre-apocalyptic adventure of a team of astronauts tasked with re-igniting the sun by delivering a massive payload in Sunshine. Based in 2057, this near-futuristic film has heavy influence from 2001: A Space Odyssey and 2010: The Year We Make Contact. With relatively unexplained artificial gravity, inner-spaceship scooters and gold leaf heat-deflecting spacesuits, many of the gadgets and technology are taken for granted in this 2007 release.

3D Projection Cube
Structured as a small room on board Icarus II, the 3D projection deck serves as a way to boost astronauts' spirits and calculate routes. Translucent walls with embedded light-emitting cells make up the entire cube of a room, allowing for an interactive 3-dimensional experience without the need for external projectors. It's unseen yet as to if this experience requires the use of optical tracking cameras for a gestural user interface. Specific cells have the ability to toggle on or off depending on the specific need of the projection. While this gadget realistically blows away any CAVE we've seen (guesstimating these visuals to be upwards of 100 million pixels), the tactile-keyboard-loving-geek in us is still unrealistically holding out for a touchable hologram to toy with. More after the break.

Not to crack open a can of worms or anything, but we're honestly curious to see what the legions of Area-51 m15x / m17x owners would change about their machines. When launched, both rigs were fawned over for their top-notch specifications, but the m15x hasn't seen the warmest of receptions from its owners. As you well know, the 17-inch sibling just now started landing on doorsteps everywhere, and we're genuinely hoping that it doesn't present those same cracking issues as found on the aforesaid m15x. Beyond defects, we also want to hear what you'd change about a flawless m15x / m17x. Whittle down the weight? Change up the style? Swap out a few components? Go on and let 'er rip in comments below.

It's that time of year again, folks (yes, summertime). Which also means vacation time for many USers, and that could very well pose a problem. All those gadgets you can't leave behind have to be toted along somehow, so we'll let Brendan explain his quandary further:

"My wife and I will be traveling to Europe for 5 weeks. Naturally, I have some perfectly portable gadgets which will need to come along, but I need a good bag (messenger or backpack style, preferably lightweight) to hold the goodies and also keep those pesky pick-pockets at bay. I've got a subnote, GPS, DSLR, PMP, pocket translator and a few other peripherals. What bag will keep all these items safe, yet not make me stand out like a big sore 'tourist' thumb?"

We're glad you asked, and we have all ideas quite a few others are too. What backpacks have you found useful for carrying around gadgetry, and more importantly, which ones are comfortable for hours on end? If you've got a question of your own to unpack, send 'er over to ask at engadget dawt com.
