All of the models feature 1 GB of SDRAM, expandable up to 4 GB (a new high capacity for the iMac line), and can house up to 1 Terabyte of hard disk storage.

Apple also made the decision to only offer glossy screens in the new iMacs. At the media event Tuesday announcing the new Macs, Steve Jobs said Appleis customers had spoken on this issue, and that the vast majority of them preferred glossy screens. Apple first began offering a glossy option on MacBook Pros in 2006.
