So, I got a buttload of cash for Christmas. I'm considering buying a 20" iMac to complete my conversion to the Apple world (added to my iBook and new Nano ). We all know that Apple is eventually coming out with the Intel based chips. Question: what is the usable life of the G5 chips and their software? Will Apple be abandoning this line, or will the transition to Intel be smooth and take a while? I'm not big on waiting for the next generation in the computer world, because it is always obsolete in a year anyway, but still... What should I do?
