The new G5 iMac is actually pretty cheap when you look at what you're getting. A 64-bit processor running one of the most stable OSes out there, very user-friendly, very robust. You won't have to worry about down times due to viruses or spyware or any of that crap. But of course, you said you have an iBook, so you already know all that:^). Good luck!
