You might want to make an addendum to your Christmas list. Those impossibly slender new iMacs go on sale November 30.
Announced in September at Apple's iPhone event, the latest desktop machines are just 5mm thin. The base 21.5-inch model has a 2.7 GHz quad-core processor and starts at $1,300. The 27-incher starts with a 2.9 GHz quad-core i5 processor and pricing begins at $1,800. Each machine can be bumped up all the way up to i7 if you please.
