Touchscreen displays are slowly making their way into the home, accelerated since Microsoft stepped up their touch functionality in Windows 7, but they're still expensive. IDTI reckon they have a low-cost alternative, however; their 21.5-inch display responds to pen input and two-point multitouch thanks to a proprietary touch technology, but best of all they're expecting to launch it with a $300 price tag.
Video demo after the cut
The IDTI screen is capable of displaying Full HD resolution video, and the digitizer technology doesn't impair image quality like you'd find with a resistive touchscreen layer. It also allows you to rest your palm on the screen without it being recognized as a rogue touch, something previously you'd required a Wacom-style active digitizer to do.
Now, in this video from CeBIT 2010, Charbax seems to think that the display includes PC components like some of the all-in-one desktops we've seen lately, but according to IDTI's site it's a standalone display only. $300 would be too cheap for a Full HD capable desktop, frankly, but it's still reasonable for a screen on its own.
