Oh, speaking about which, my cousin (surprisingly) able to play Minecraft on just 64 MB of physical memory and 3 GB of Virtual memory set with a page file setting on a Packard Bell 7950C with an Intel Celeron 400 MHz with Windows 98, I was surprised he could legitimately play MC on it! Almost always if you tried playing Minecraft, (or most newer games), it would usually not work out that good
==On topic part==
I would think Windows 7 is definitely better than Vista.

Also, supernotch, you said "Windows MB", you must've meant "Windows ME"? And, the computer I just mentioned, that was also definitely an Old Potato. Running successfully with ABSOLUTELY NO MAINTENANCE/REPAIR NEEDS of any way, (except for some software problems) since 2000.
