Samsung Tablet PC model NP-Q1 touchscreen, with a 900 Mhz processor, 1 GB RAM, and installed with Windows XP Pro 2005 SP2. It also has a bootup option for a special XP setup called MobilEyes which I think is for the visually impaired. This computer is like brand new condition, we believe this came directly from a Samsung employee and probably wasn't used much. Comes with a ton of extra goodies in similarly minty condition like a keyboard/mouse combo, USB hub, original power supply, Samsung protective sleeve, and another holder, external DVD drive, metal installation bezel, and a memory card reader. Computer, stylus and touchscreen all function great like this thing never got used!
