I just got this machine for my wife from Amazon.com. The 2.4GHz 24" iMac with 1GB RAM and 320GB HDD. $1794 before $100 rebate. An additional 2GB Crucial RAM for $58 as well. All of this with free 2-day UPS shipping with Amazon Prime. It appears Amazon.com has recent stock as mine has a week 52 build of 2007. No issues with screen brightness or uniformity and no over-heating (so far). I had low expectations, but its a great machine and the glass screen actually protects against kids ruining the LCD. I got used to the new keyboard very quickly too. My wife needed a new computer now, and I was going to get the Dell XPS 420, but I recently got some high-end Dell's with Vista at work and the OS is a turd. The hardware is quite good, but the OS really ruins the machine. The wife didn't know about me ordering the iMac, but was pleasantly surprised, but still no sex for me. And I even got MS Office for her too! Can anyone recommend which external hard drive I should use for backups with Time Machine?
