XP

Best OS /highfive ! :D

7 isn't that bad, really. :)

(8 sucks, tho.)

I won't lie, I do want to try Win 7, but as GameRager said, I doubt my system could handle it.

I'll get Win 7 ones XP really recieves no Updates anymore. :P

I was hesitant to switch as well, but once I tried it there was no going back. The only downside(imo) is the insane memory usage(I think 7 needs 500mb just to run itself.)

Use proper architectures. 32-bit applications running on a 64-bit OS use double the memory.

Not all older apps/games have 64-BIT architectures. ;p

(Also as I said, Win 7 uses a ton of RAM just by itself.)

I got 2gb of ram that's not the prop I will upgrade to 4gb sometime soon anyway but just XP is the thing I grew up with and 7 is like meeh.

Think of it like shoes....you gotta change those every so often too, right? Think of it as a growing experience.

Also a detailed list of Reqs in case you/others are interested: Win 7 Requirements

Easily got all those req. but well... waiting :p

Yes, like Firefox for example. Using Firefox on Win7 uses double the RAM amount, unless you go for nightly builds or one of the derivatives.
As for the rest, I was running Win7 on an older Fujitsu with 512MB ram, and was also able to play a few games (though the integrated graphics really killed it).

More like 1 Gb. To perform basic everyday tasks - 2 Gb. I mean comfortable work, not that load it from swap thing. Games start at 4 Gb :)

Your call.....if you ever want to dabble in it you could always dual boot and test it out(That's how I got into it, btw.)
