Really depends on application compatibility for me, as much as drivers, so I voted Dec. If it ain't broke, don't fix it...
I'd have to agree w/ that... totally in fact!
* That WILL work for me, & has on previous "OS transitions" in the past, all the way from Windows 3.x/DOS -> Win9x -> NT-based OS!
(Present really as far as Windows NT-based/heritaged OS since NT 3.5x, which I ran concurrently w/ 9x mostly over the 1994-1997 timeframe, when I went over to NT-based stuff totally for, when Win2000 came out & was SOLID, for BOTH apps + drivers-wise).
Honestly? I'd love to run it NOW... I like how AERO GLASS looks, & I do respect some of the stuff you do NOT see in security features in this new OS from MS!
HOWEVER, I am not sure, for example, if the caching SATA/SATA2 controller I have from Promise (SuperTrak) has a driver for VISTA ready... Also, I know that NVidia (whose video hardware I like due to my like of OpenGL (really, IDSoftware)) isn't totally ready either.
* So, presently @ least, what's the point of my going to VISTA now? None, imo... not yet, driver support for the hardware I use is possibly incomplete OR 'spotty' still, NOR (edit part) do I like the "DRM" arm-twisting that's going on to/with MS, or the OpenGL gaming mess either.

P.S.=> The drivers mess will clear up, eventually, if the vendors of said "problem-child" hardwares want to stay in business over the long-haul imo... apps will MOSTLY be OK (Win32 usermode ones, BUT not ones that combine in filtering drivers usage like AntiVirus etc. though, or for "BLOCK DEVICE DRIVERS" which talk to your harddisks & then to filesystems drivers, for example, this may be a problem spot too @ some points imo as well)... apk
