After all my hard work i restarted and started to clean up my drives, moving things where i wanted them only to have Vista freeze on me everytime it moved a file larger than 300mb...
That has been fixed in SP1.
ista is all cosmetics and it doesnt use any new features really exept UCA (witch is meant to me annoying) and the indexing thingie). Thats the only two things you notice is new.
There's also new troubleshooting tools, Flip 3D, DirectX 10, protected mode for IE8, SuperFetch and ReadyBoost, improved backup tools including disk images, a new sidebar, and a few other things. In addition, a lot of existing stuff has been completely rewritten, which won't be obvious to the user but will be very obvious to the developer. It's a lot of small improvements instead of a few large ones.
I *do* recommend getting Vista with a new computer instead of trying to put it on an old computer. It works best on new machines.
