Travel chess, LCD with keypad to enter the moves and magnetic pieces. It's smilar to the Novag Solo, thou this one is smaller.
I know of another version of this model which has an extra row of keys. You can see it here: Alain's Zanchetta website
It's not a strong chess computer as you can see in the rating but it's an interesting unit and it's extremely portable.
