It isn't Vista's abilities that bother most people, it's the sheer number of incompatability problems that people don't like.
Just to let you know, MS knew there were going to be several incompatibility issues with Vista. They actually prepared for it though. Right click on the program that's screwy, "properties," click the little "compatibility" tab up top and choose "run in compatibility mode for" and you can go all the way down to Windows 95. I've gotten old school games my daughter likes to play that used to just shut down.
I'm not advocating Vista, my favorite OS is still 98SE, but like the wolf man said,
its like an old lazyboy
You'll get used to it after a while, but it's going to take some time and regular use. The alternatives...don't use it, or cry about it.
Computers are always changing. I may wait a year or so for them to get the bugs out, but I like to stick pretty close to the times, at least for technology. I finally let my obsession with EQ go now that they've completely screwed up the PVP server with all these expansions. But then again, SOE never listens to their players. Mythic seems like they actually give a damn.
