Assuming you have a 32 bit processor and the minimum requirement for Win 7 32 Bit is 1 meg of ram, that means you have .256 gigs of ram? Dude a 1 gig stick will cost $30 or lower if you shop around. Also, unless you have a computer from the 90's then a processor should NOT be a problem. Win 7 runs fine on netbooks.

I would say it depands on what you use your computer for and how old and what kind of system you got. There are different kind of users who will prefer different operating systems. So it's a bit hard to clearly state "this" is the best OS.

Mac users are in general stuck with Mac OSX, so they will probably say it's the best. Lot of "expert" users, developers and administrators are likely to go for some kind of Linux distrubition. But for the average user who just likes to play games and watch pron online Windows is for sure the best choice. You only left with the question, which version of Windows.

On my old Pentium III en 4 i used Win XP (and different versions of Linux for testing purposes), and it always worked fine, did everything i wanted it to do.
On my new system i have been using Windows 7 64bit version for a while and i have to say it runs way smoother than XP, although i still like XP's interface better (but thats just a matter of taste). I would say for the average user, with a pc not older than two years, who plays games a lot Windows 7 is surely the best choice. For older computers XP is still the best option.

He said Vista.  Win 7 has lower requirements for RAM.

actually it does

i tried it and it works fine

Even better, Vista has lower minimum requirements on Microsofts site. 516 megs of ram is required. 1 gig would work even better.

Windows 7, because it's the most stable OS from Microsoft, since, like, ever.

Windows xp is showing its age.

Windows 7 is the best in every concievable way.

Yes Windows XP uses less memory, but hey, the damn thing is 10 years old of course it will use les memory! Anyone who doesn't have a computer capable of using Windows 7 is probably 5 years overdo for a comp upgrade.

true

Windows 7

Windows 7 for me because it's what I'm used to and it's done right
