If you don't want a laptop I would think about a mobile phone with internet access, unlike the pocketsurfer (I have one and it's awful to use) the screen will be a touch one and text input will be easy, on the pocket surfer it's torturous. Also 20 hours a month free access provided by the pocket surer will not be enough for a young lad, my mobile phone offers umlimited internet access and it's fast access, easily as fast as the pocketsurfer if not faster.
On the whole I'd avoid it, it's clumsy and not user friendly.
