vista is the worst operating system that I've used , w7 is much better and easier. If you make a choice between them, I for w7, but not for the fact that I like it, just because don't like vista.
I had used windows vista for 2 years, and I liked, it was good, but still I recommend you use, Windows 7 even for 512 mb RAM, it works pretty fine.
You're, probable, one of the exceptions of the rule, if you finded it ok to work with it. Why have you decided to upgrade for Windows 7?
Windows 7 is far superior in quality, speed and alot alot of other things....windows vista has such a bad reputation...I remember using it and hating it and went back to XP waiting for the new windows...so easy choice.
I use vista for 4years. In the beginning there were problems with the software. But the service packs have solved these problems. This year windous7 used during the month. Overall, I enjoyed it. But I'm very accustomed to vista. So went back. I see no particular advantage in windous7.
You seem to be very lucky, if you've managed to cope with all problems of Vista. I mean, I haven't had enough patience to put up with its flaws myslef, and none of my colleagues, for instance, has either.
