HTC may have unleashed a completely unique Android tablet with an active digitizer and stylus yesterday, but more are on the way. At least that's the word from N-Trig, the company responsible for the screen and pen technology in HTC's Flyer as well as other convertible tablet PCs. According to the company's VP of Business Development Lenny Englehardt, 7-, 9.7-, and 10-inch pen-equipped Android slates are coming in the next year from major manufacturers (sadly, he couldn't share which ones). We went over a bit of the hardware technology yesterday and dug a bit into HTC's pen-optimized Scribe software, but the big question on our mind has been third party Android applications that take advantage of the stylus. Well, it turns out there are quite a few of them in the works from the likes of Adobe and others. And yes, one of them includes handwriting conversion! We got a look at three of those forthcoming apps on N-Trig's Tegra 2 development kit, which has the same screen / pen hardware as the Flyer -- hit the break for our impressions and a video demo.
