Apple is now accepting orders for the new iMac on their online store. The new iMacs offer dramatically reduced thickness and add a brand new Fusion Drive that combines flash storage and a traditional disk-based hard drive to maximize both speed and capacity. The 21.5" model starts at $1299 and $1499 while the 27" model starts at $1799 and $1999. The 21.5" model is shipping in "1-3 business days" while the 27" model ships in 2-3 weeks. Limited stock of 21.5" iMacs should also be available in Apple retail stores starting today. The previously reported iMac build-to-order options were accurate with a variety of RAM, Processor, Hard Drive and Graphics Card upgrades available for specific models. We previously posted an unboxing video of the new iMac. Article Link: New iMac Now Available to Order in the U.S.
