Here's the situation. After shopping around for 2 weeks I have determined that for the same price I can purchase either of the following. 20" iMac with 1 GB RAM and AppleCare or 1.8 GHz G5 with 1 GB RAM, 17" Studio Display, AppleCare I like the bigger monitor on the iMac, but I like the ability to upgrade over time on the G5. (Is the 20" Cinema Display worth the extra $600?) I will keep the computer for 3 years. Which one do I buy and why? Thank You!!!!!
