I swear I'm not trying to pick on Joe lately. He's a great guy. I'm just not sure what the heck he's talking about here. He says that he tried reproducing the searches in the Launch demo when he got home, and he couldn't. He then draws the conclusion that advanced Vista searches require SharePoint (unless I'm reading it incorrectly).
The demo he is talking about (I presume) starts at 12:45 in the on-demand webcast. I re-created it, as close as I could, in this video:

As you can see, the filtering is easily done. So what couldn't he reproduce? I don't know.
None of that invalidates his other arguments, though. WinFS is still sorely missed, and Search is not the silver bullet. But Search in Vista & Office is vastly improved over XP, and has saved my butt on more than one occasion.
I'll tell you what though, I learned a couple things from that webcast... which I wasn't expecting. I had honestly never tried filtering like that before... it was wicked cool. I also didn't know about some of the things Office was capable of. I love how, even after three years of testing, I discover new things about Vista. I hope that doesn't stop for a while.
At any rate, I just wanted to clear that up.
