HP comperably equpped (no tv tuner, 2.8GHz, 8GB 1TB, but lacking wireless keyboard, webcam, and microhpone Mac has) came in over $2100.
27" iMac 3.06 Core 2 Duo with same is about $1800. and has a slightly faster Radeo 4670 GPU as well, not to mention a much better IPS display panel with 4 more inches and nearly double the resolution.
21.5" imac is a bit smaller, but still higher resolution (even given the 1" smaller screen), still has a 3GHz cpu (and could be 3.33 for another $180), still has the better GPU, and is closer to $1600.
You can add a TV tuner to a Mac cheper than what HP charges for one, and a copy of parallels can be had free from many vendors and a copy of Win 7 is $49 as well, so for several hundred less, simply saccrifice the touch screen and you do in fact get a MUCH more powerful machine that runs Windows AND OS X. (or, and the iMacs can be upgraded to 32GB of RAM (16GB factory direct across 4 DDR3 slots). The HP maxes out at 8GB using slower RAM. Essentially, this is a $600 premium, saccrifice of webcam options, lack of OS compatability, and a slower machine for a touch interface.
...or, as rumor speculates, for $700-800 you'll be able to get an iPad in a couple of months with NFC, and put it in front of that iMac and use it as a touch interface for it... I'd much rather have a more powerful Mac with more and better options AND an iPad for a $100 premium than have this HP. They priced this out of reality.
