I currently have a Dell OptiPlex GX520 with 2GB RAM, Pentium 4 3GHz and it currently is running Windows XP Pro. I need to reformat my computer, and I was wondering if I should go ahead and upgrade to a new Operating System. I was thinking of Windows 7 or Mac. I am already comfortable and cozy with Windows XP. Is it worth reformatting with Windows 7? I'm just a bit worried all my programs will not be compatible with 7, even though it has XP Mode. Then I thought about Mac, but I wasn't sure if it'd be worth finding all new programs that work for Mac.
So basically, tell me what operating system you have, what you like and don't like about it, and any recommendations you may have. Thanks
