I am thinking about replacing Windows XP with Linux. I have a Dell Inspiron 1525. Intel Core 2 Duo CPU. T8300 @ 2.4GHz. 2.39GHz, 2.99 GB of Ram. 300GB hard drive. When I was in high school I got my A+ certification, but that was with Windows 98 and DOS, so I realize a lot has changed since then, but I do understand the basics of computers. I was wondering what would be the best version of Linux to install on my computer and how I would go about it. Do I need to install Linux on a separate partition from Windows? What do I need to replace my current programs: Microsoft Office, Realplayer, Paint (for my daughter), and will I be able to run the only game I play on my computer, Sim City 4? I am not concerned about Internet Explorer, as I have been using Firefox for about a year now, and I really like it. Any help would be greatly appreciated. Thank you.
