This may look like an oversized lipstick, but it's a device that will make you go 'wow', may even tempt you to part with your cash, use once and then leave forever in a draw.

Called the Celluon Laserkey CL800BT, it's a laser keyboard that works with portable, Windows or Symbian devices such as PDAs or smartphones. It also works with the Crackberry, should you be addicted to yours.

The idea is, carry this, sync it to your PDA or phone, and you can type away. The virtual keyboard on any flat surface looks very sci-fi and catches your eye, so it has great novelty value. But then you start wondering why, especially at £129.

It's a bit pointless, but if you have money to burn and want to impress friends (or look slightly odd on the train, as you tap away on the table in front of you), you can read the full review of the Celluon Laserkey CL800BT on sister site PCW.
