I have an older model PC that I'm giving to my sister. It's an HP 8755c with ME installed. I have already added 512 KB of RAM and a 80gb HD to it. Here's the question: Do I need to upgrade ME to XP or Vista? She's only using it for CD burning and checking her E-mail and such. Very very basic stuff! Will Real Player, Nero, Windows Media Player all work with ME or should I upgrade the OS to keep up?
