Well, I'm on for Windows Vista Beta 2, and have spent a couple hours testing apps.
-Autorun.INF, Backup, Sync, and Log were tested.
-All ran without a hitch.
-Backup works with both zip and 7z formats.
-Sync was tested with two new test catagories, and worked great.
(NOTE: Steve, maybe a refresh button for the categories after changing them, as it requires a restart to see changes/additions.)
-John T. Haller's Portable Appy Goodness
-Portables: Abiword, Firefox, Thunderbird, Gaim, Miranda, FileZilla, OO.o excluding base (not tested), VLC, SciTE, ClamWin, GIMP.
-All worked fine
-Misc Other Apps: EssentialPIM, HydraIRC, FoxIt PDF Reader, FastStone Image Viewer, A43 File Manager, GetDiz, NotePad++, Portable Notepad2, KeePass, SpyBot S&D, PortableNSIS, CyberShredder, Portable Norton Partion Magic v8.05 (Find it yourself, I legally own partition magic and I'm not sharing.)
-Not Working - Various Issues-
Portable wxDev-Cpp, CPU-Z (partially works), PC-Wizard, Portable Scribus, NVU (PA.com) , Sunbird (PA.com), Portable Wackget.
If you want any portable apps tested post them here (links) and I'll try em out.

Vista looks good, very "pretty" but takes away a *LOT* of user control. Very Dumbed Down.
