You like the idea of an HP TouchSmart, but you'd like to keep your existing computer? Dell's SX2210T is a 21.5-inch multitouch monitor without the all-in-one PC attached.
Despite being discovered on Dell's site, the monitor hasn't been officially announced yet. We assume the system is IR-based (meaning it's limited to 2 simultaneous touch points), tracking a finger and stylus alike as you drag and drop or pan/zoom.
Otherwise, specs are like any other monitor, with 1920x1080 resolution, 1000:1 contrast and quick 2ms response time, along with HDMI/DVI-in and a webcam/mic combo. No word yet on pricing or release, but we like the idea. A lot. [Dell via Engadget]
