Sony are planning on updating their old Airboard, but no trying to even compete with the GBA, instead they are aiming for over 40s.

The Airboard is 2 year old product that is classed as a "smart" LCD that can be connected to your entertainment system and can allow you to watch TV and DVDs anywhere in the house.

Apparently the over 40s love the Airboard and take up a large percentage of the userbase. Sony are planning on releasing downloadble games such as Othello and Go (of which Hiroshi Yamauchi is a master) for it. The Airboard is low in production and high in price though so it is not aimed at a wide userbase.
