Although I use Linux most of the time, have ran VISTA on a couple of computers with no issues and like the features it has. I tried service pack 1 pre release for VISTA and it installed without issue but took quite some time. Then I found out that it stuck a message down in the lower right of the desktop and too had an expiration date of June as I recall and would have to be uninstalled before the released service pack would be installed.
As there was no issue with hardware, etc., with both computers, took it off.
Funny over the years that when Windows first came out many still did much from the DOS Prompt and there were many of the same issues we hear about today?
There were issues with drivers for hardware when XP came out some companies would not release drivers for some of their products!
Think VISTA will be around about 5 years like it or not?
After spending some time with it and the some of the driver issues are resolved, you will find it is all not that bad!
