HP's TouchSmart sub-brand and its other AIOs should be no stranger to many PC advocates, but in case you've never come across one before, the company's laid all of them out on one side of its Global Influencer Summit in Shanghai. Models range from the TouchSmart IQ770 launched back in 2007, all the way to the recently shipped Z1 workstation and even the just-announced t410 Smart Zero Client; but the real gem of the booth is that little beige HP 150 right in the middle -- it's one of the first-ever touchscreen PCs, dating back to 1983, powered by an 8MHz Intel 8088 chip, ran MS-DOS and cost a mere $3,995.

Whilst on the topic, HP's Vice President of Industrial Design Stacy Wolff shared some interesting stats: his team found that much like laptops, there are very different screen size preferences across different regions, with the US showing strong interest in 20-inch and 23-inch HP AIOs, whereas China much prefers 20-inch over 21.5-inch and 23-inch. With the big jump in AIO market penetration in each region between 2008 to 2012 (almost doubled in Japan and the US; and an even bigger leap for other markets), HP predicts that these machines will continue to steadily increase market penetration across more price points -- this was illustrated with what it conveniently calls the "AIO wedge" on a chart. Feel free to take a gander at our gallery for more tidbits.
