You didn't really think we'd make it through his retirement without running the sexiest of all Bill photos, did you? We have to wonder what he'll feel like tomorrow morning, though -- we hear the headache on a 33 year software hangover is absolutely vicious.

Anyhow, just because the man's left the building doesn't mean you can't take home a few of his fine products. Hit the contests below, they close up Sunday night.

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.

It looks like there more than a few misty eyes around Microsoft's Redmond campus today, where even the man of the day himself wiped away tears as he bid his official farewell to the company. According to Reuters, Gates was joined on stage at the employee-only event by CEO Steve Ballmer, who reportedly got choked up himself as he heaped praise on Gates, saying that "there's no way to say thanks to Bill. Bill's the founder. Bill's the leader," adding that, "this is Bill's baby." Ballmer also talked about how he had contemplated leaving Microsoft just a month after joining the company, only to have Gates persuade him to stay by saying "You don't get it. You don't get it. We are going to put a computer on every desk and in every home." Say what you will about some of his predictions, but he was sure on the mark with that one.

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.

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.

The end of an era; a fresh beginning; good riddance -- whatever you think of Bill's final day at Microsoft, it's impossible to deny that his tenure there helped forever re-shape not just technology, but the world as we know it. So we're declaring June 27th Bill Gates Day here at Engadget and hopefully you'll forgive us for, like, totally tearing up now that he's finally stepping out of his role as nerd-baron and into the shoes of full-blown immortal philanthropist. Hey, it's Sir William Henry Gates III's world, we just live in it -- that means you, too, Steve.

We'll miss you big guy.

P.S. -Keep this on the DL, but we heard this rumor he's thinking of returning to uni for his post-post-post-doc, and it won't even be honorary. We'll keep you posted. In the mean time today, expect plenty more Bill.

Man, who could have predicted back in 1978 that this collection of nerds, dweebs, and hippies would come to rule the desktop? A time when a PC in every home was just a vision and 640KB of memory ought to be enough for anybody. That's the original Microsoft "family" re-photographed 30 years later (minus Bob Wallace who died in 2002) in preparation for Bill Gates to slip into tomorrow's smoking jacket of retirement. It's better than a gold watch we guess. Who's who after the break.

While Bill Gates' imminent retirement from Microsoft is understandably a cause for some quiet moments of reflection for some, it's also given folks an excuse to dig up some tidbits from Gates' tenure that have somehow gone unnoticed or unheralded in the past few years, one of the juiciest of which comes in the form of a 2003 email that Todd Bishop of the Seattle Post-Intelligence has thankfully given fresh light. In it, Gates rips into "how Windows Usability has been going backwards" as he details his long, arduous attempts to download Moviemaker and buy the then new Digital Plus pack. While there's far to many gems to include here, a few of Gates' stand-out observations include how "crazy" it is that it took six minutes to install "a bunch of controls" before he was able to install Moviemaker, and his disappointment that he had to reboot his machine even though he reboots it every night. Eventually, after (apparently) getting Moviemaker installed, Gates decided to go digging in the add/remove program options to ensure that it was installed, only to find it missing, which prompted him to declare that, "someone decided to trash the one part of Windows that was usable," adding that, "this program listing was one sane place but now it is all crapped up." Needless to say, we'd recommend hitting the read link below to check out the full must-read email.

Gates and Ballmer are down at the WSJ's All Things Digital conference to talk tech with Mossberg and Swisher, and it looks like tonight they'll be unveiling the first (official) glimpses of Vista's successor, currently known as Windows 7. We'll be posting live from the event, so be sure to check back at 6:15pm PT (9:15 Eastern) as things kick off.

See that 15-foot beam of glowing manhood? That's Bill Gates. While cohort Steve Ballmer was being pelted with eggs by angry Hungarians, Microsoft Chairman Gates was making a virtual appearance at the World Congress on Information Technology 2008 in Kuala Lumpur. The crowd cheered -- or screamed in terror -- as the giant 4.6-meter holographic specter assured them that technology is, in fact, the future. Said the chairman, "There are one billion people who have a personal computer each but there are five billion others who don't. Microsoft also wants to reach these people." We're hoping that Bill has recorded several hundred holographic speeches and will continue to grace conventions' presences for years, and years, and years to come.

If your pants / panties were in a "bunch" upon hearing news that Windows 7 would be headed into your ever-loving arms "next year," you might just want to hold off on those party invites for a little bit. Sure, Bill Gates just happened to mention that we'd see a new version of the OS "Sometime in the next year or so," but it's looking like that "or so" makes a world of difference. Microsoft wants to chill everyone out with the somber news that its got no plans to introduce Windows 7 any earlier than January 2010 (three years from the launch of Vista), and reassure us that crazy old Gates may have just been talkin' developer speak. "As is standard with the release of a new product, we will be releasing early builds of Windows 7 prior to its general availability as a means to gain tester feedback," a spokesman for Microsoft said, downplaying Gates' statement. Of course, this means that XP's cutoff will suddenly move even further down the line, which makes us wonder what the point of setting that June 2010 date was in the first place. Why are you toying with us like this, Microsoft?

[Thanks, Tony]
