I have super powerful machine now and and I've been running it since the first day. All I can say is Vista simply sucks ! It's full of bugs, don't even want to go into detail it makes me sick how stupid mistakes MS did. I was thrilled at first like millions of others out there, but now when it actually stays on my way to do my business properly, Vista only gets on my nerves. They rushed everything just for the competition sake, nothing else. OS is obviously not finished and the biggest proof for that is that they already released a bunch of updates, and what's even more sad, not talking about security updates, but so called Performance updates. Incredible stupid mistakes, that's unbelievable... simple copying of a large number of files takes forever, GUI notification about approximate remaining time to finish this task, is not even close... millions of small errors and bugs. Just try to open Flash CS3, Photoshop CS3 and Illustrator CS3 in with some 300 Mb large AI file inside (sorry, but that's how it is when we do our designing business here, especially when NIKE and MINI moris are sending us their story boards). Vista slows down to a crawl. 2 MB of DDR3 doesn't help much, Intel Core 2 Duo doesn't help much... so what do they need ?
It is all nice and pretty, but beauty doesn't last for long... just like in real life. In this case I don't need bells and whistles, I need productivity, and that's what's missing here.
It is very sad to say that I'm forced to boot into XP more often than I can count, so I can finish some of those tasks on time. Yes, it's not that pretty, but XP does it without a problem.
All this helped me to slowly switch to Apple... 98% of designing world in here is using Apple and that simply became standard. With these wonderful new iMacs and super low prices, you simply can't beat those deals... Apple is finally entering out world in a big way.
I'll keep PCs no question about it, but for once let's be realistic. Even PCLinuxOS that I run on my other machine works better than Vista. MS screwed up this game, no question about it...
