I'm sure that most of you will say that the new Rev B iMac is a much better deal but...it's a bit difficult to shell out $1800 for a computer, you know? Especially with the WAF. I currently have a 1Ghz G4 17" iMac. I love it and I am a pretty heavy iLife user. I make tons of movies and put them up on homepage and make custom DVDs for family/friends. I'll have to sell the G4 iMac, which will be a sad day. I'm interested in moving to a G5 to speed up rendering effects in iMovie and DVD encoding in iDVD. I may start making short films so maybe even move up to FCE. I also want the 20" LCD, as an upgrade to my 17". I really don't need the new iMac but I just have the itch to upgrade. So what would you do? Grab the Rev A 20" or go all out on the new one? Or keep my beautiful G4 iMac?
