I've got Vista and .... well ... it sucks. Its more annoying to use than XP, and shortcuts are replaced by marathon clicking bouts. Sure, its easier for a moron or a more casual user to use. But... I'm an IT professional.
The security features suck monkey balls. Few developers live up to the specs of Vista. If they did Vista would be rock solid and ten times safer than XP. But they don't, so it doesn't work. Everything teeters on the brink of crashing all the time, and eats up all memory.
I'm considering throwing it out. Vista sucks!!!
