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.

Wednesday night's Jobs and Gates intimate sit-down wasn't just civil, it was downright reverent -- at times even tearful. But we all imagined alternate realities and an overflow of events that might have transpired in another universe... now vote.

P.S. -Feel free to leave your own in comments.

We kind of never thought we'd see the day where Mac and PC voluntarily shared the stage on neutral ground, but that day is today. Very soon Bill Gates and Steve Jobs -- both pioneering execs that need absolutely no introduction -- will sit up in front of the audience here at D and discuss god knows what. Don't miss this, people, who knows if this will happen again in any of our lifetimes. You'll know when we get started. Who's got odds that they don't walk out and say "Hi, I'm a PC." "Hi, I'm a Mac."?

We're in! They're playing the Beatles, just like they did when Jobs came out the first time.

Update: Video recap online! Right after the break, but before the rest of our coverage.

Steve Jobs is up here in just a few, everybody. It looks like we can probably prepare ourselves for an update on the iTunes shift to no-DRM, the status of the iPhone, and whatever else is on El Jobso's mind. It's all on Mossberg, so hopefully he'll drill down deep to the topics we hold near and dear. Stay close, you'll know when it gets underway! (Note: Walt's questions are in bold.)

UPDATE: D has posted video highlights of Steve's and Walt's talk, our original liveblog follows after the jump.

Steve "Developers!" Ballmer is set to take the stage this morning at D, but since we don't know exactly what time that's going to happen you all are gonna have to hang tight until he does. We expect he'll be discussing last night's Surface announcement, but we'll see what else he's got planned for us. Stick close!

UPDATE: D has posted video highlights of Ballmer's chat, our original liveblog after the jump.

Woops! Looks like someone was trigger-happy at Palm and shot out the press release for tomorrow's announcement a little too soon! Apparently what Jeff Hawkins is going to announce in the morning at D is called the Palm Foleo (a name we've heard rumored before), and is being positioned as a "smartphone companion". We didn't know our smartphones weren't quite smart enough to need a guide to the interwebs, but the Foleo syncs to your mobile device, providing a full size keyboard and larger display for editing documents and triaging email (among other things). So yeah, basically it's a dumb device piggybacking all your Treo's most useful feature -- its connectivity. Apparently users can expect instant-on access, five hours battery life, Palm's new Linux OS, and a $500 pricetag to round off that Treo kit to about a grand this summer. Assuming all this is indeed the case, we can only come to one conclusion: damned if we need yet another friggin device. Seriously, please Palm, what we need is for you to improve the Treo -- or whatever phone device you expect us to carry and use -- not design the Treo its very own Lenny Small to hack around sluggish handset design. The yet-another-device philosophy doesn't carry, so to speak, and it's sure as hell not the future of mobile computing.

P.S. -No, that's a jokey Sony UX UMPC to the right, not the still-unseen Foleo.

If ZDnet staple Mary Jo Foley (or more specifically, her source) is right, we may be seeing Microsoft take the next big step in device interaction at tomorrow's D: All Things Digital Conference, with the perennial Redmond watcher predicting an official unveiling of the company's PlayTable / Project Milan multi-touch, gesture-based input technology. PlayTable, which combines elements we've seen in the iPhone, from NYU's Jeff Han, in various prototype devices, and from Microsoft's own, recently-demo'ed DigiDesk, is envisioned as a multi-purpose interface that can be employed in anything from a DAP (Zune) to a cellphone (WinMo handsets) to a gaming console (Xbox) -- so it's no coincidence that the project is being developed by the same Mobile and Entertainment division that's also in charge of these categories. All in all, tomorrow promises to be a big day: not only is Palm making a potentially breakthrough announcement, and the faces of Apple and Microsoft scheduled to appear together on the same stage, but we may also get to witness computing history to boot; man, if we had real jobs, we'd be calling in sick in a heartbeat.
