The Touch Book is a real netbook with a detachable touch screen, smaller keyboard, small price tag, but generally a miniature notebook. It comes with Touch Book OS, but claims to run Ubuntu, Android, and Windows CE.

The CPU is an ARM chip from Texas Instruments, the OMAP3530, running with 256MB RAM and 256MB of NAND memory. There is no hard drive — instead you get an 8GB SD card. You’ll also find Wi-Fi, Bluetooth, a 3D accelerometer and three USB ports. The display is held in place by magnets.

Price? $300 for the tablet screen, or $400 with the attachable keyboard. Would you buy a similar sized multi-touch Mac with an attachable screen that runs Mac OS X and iPhone OS? What would you pay?
