Become a MacRumors Supporter for $50/year with no ads, ability to filter front page stories, and private forums.
I basically don't upgrade and also replace every 3 years, so after-warranty support is not an issue. However there are some things I don't like:

1. Too much form over function -- how about a couple of front facing USB ports? Superdrive slot tends to scratch media and can't be used with second monitor to right of iMac.
2. At this price, and with the claims of quality, 3 year Applecare should be standard.
3. Needs a matte display option.
