I've been beta testing Vista since M$ released the first version and I must admit I had some serious issues with RC1 & RC2, things like a program would crash, you check online for a fix and Vista says "This will be fixed in the final version".Anyway I recently received RTM build from M$ and I must admit its amazing, and yes some elements are MAC clones but other features such as Windows DVD Maker etc just add delight to the OS. Its stable, no driver issues, self cleans without user interference (If you're busy it will wait, even if midway through)...Auto update on certain OS drivers is clean, takes less space than XP and on a final note, I'm running the Ultimate version which M$ says won't run on my machine:P4 HT 2.93Ghz1Gb RAM80Gb HDDNvidia Geforce 6200le (128Mb onboard 128MB Shared)It runs perfect, no slow down, no hang, no problems, even with Aeroglass on...Anyone thinking of upgrading to Vista, I'd recommend it. Just one thing, if you don't have a TV tuner, don't bother with the Media Center element.ION Storm
