Hello I saw the IQ512 (500 series) have entered consumer retail in Sweden, sold in many of the electronic store outlets.

It was kind of a Deja Vu for me to discover this product, I came to think of the Sony 'all-in-one' desktops (PCV-W10,W20,W30) that were a fresh cosmethic departure from the stereotype computer system appearance when it came out many years ago (Pentium 4 days) although here we have touch and considerable more sophistication..
 

 I tried it out briefly in the shop.  The Photo Album functionality worked smooth and slick,

however the *main* Touchsmart interface (the main one with bigger upper line of tiles and a smaller line of tiles underneath) had some problems with jerky motion when dragged. I don't know if there exists settings for changing how the touch interaction works with the touchsmart graphics when dragged ?

As it appeared, when the user drags the finger on screen the graphics attempts to move promptly tied to each coordinate change, and performance isn't up to having that appear in an exact flow but some lag occurs here and there where the graphics has to catch up with finger motion, thus jerkiness.

I would rather prefer a "rubber banding" relation to the finger position so that the graphics move decoupled from the exact finger coordinates but move smoothly in the direction of the finger movement. This gives a more sophisticated feel to the whole experience.  Again; I am not sure if there are settings to tweak of if HP are doing revisions that improve on this ?

That issue is actually at the heart of Touchsmart market success since the customer first impression in the store is what's going to sell the product.

Anyway; bold move by HP and a refreshing alternative to the desktop box models that have looked the same for decades.

 The most common question I see appear in consumer forums regarding this concept is:

"Does it have a video output" ?   People figure it would be cool if they could connect it to their big screen living room plasma or projector over HDMI or DVI to play movies on their ordinary big screen.   (As they would if they bought some conventional PC such as all the other ones in the shop). The market penetration of flat screen TV's is massive over here, almost everyone own one in some kind of size.  People with existing living room TV's might not move over to a 22" as their only screen. So they will end up with two independent systems. Apparently the TouchSmart IQ design philosophy does not include an external monitor use case. Maybe somebody can elaborate on what forces that design choice ?

A workaround for that case could be connecting the IQ to a Media center "tank" for such output. Such as a Popcorn Hour A110 or similar over USB or Ethernet, but I don't know the usability caveats from doing that.
