I'm biased, as I prefer only to work on Apple computers. My dad is a freelance graphic artist and that's all we ever had in the house. I have a first generation iMac that still works like the day I bought it in 2001. I've seen people throwing out 4 year old Windows based computer because they were pieces of s***.
I suggest going to link [www.apple.com] and looking at their eMac line. They computers are relatively inexpensive and are awesome machines. I'm getting one just to upgrade my system. I don't really need a new computer, I just want one.
