LOL! I don't use an iMac, but I do have a Mac G4! And they are so simple to use. I use a PC at work and I would NEVER give up my Mac. But I do have an iMac.
This monster has WindowsXP and is definitely not for a beginner.....like I am! My hubby has worked with Windows98 before and now he kind of wishes we had that instead of this. But we're both slowly learning how to use it. I doubt I'll ever master it. LOL!
