Here's my Vista story:
We had an Vista computer (Dell Laptop) and have been trying it for 9 months, thinking: "You'll get used to it... eventually" - NOT. Kept crashing on stand by, starting up took an eternity, my favorite programs wouldn't work (Nokia Suite, Euroglot, Mailwasher, Outlook Express doesn't exist - replaced that by Thunderbird, EZ-Back Up, Media Player Classic, had to change the standard user to admin for every Firefox upgrade and there was more that I can't remember right now), hardware doesn't work properly and that annoying UAC that kept switching itself back to "on" every time I had disabled it.
Then Vista wouldn't start up properly anymore, and started repairing during startup till one day it finally permanently crashed (remember, no backup due to no EZ-Back Up software), and that was it! Back to XP!! That was the happiest moment for this computer; everything on the computer that didn't work before magically started to work: The mouse functions, the built-in wireless network connection (we had to buy a USB device because it wouldn't work), the standby function when closing the lap top and the speed... it looked like the computer was struck by lightning! (1.73GHZ Intel processor and 1GB RAM).
When Vista ever becomes the standard, I will seriously consider a
Dell with Linux Ubuntu or Apple (that new
MacBook Air looks very sexy to me) - definitely no more
Vista for me, ever!
