It may be called the Game Boy Advance but don’t let that fool you into thinking it only plays games. You could also use the GBA as a videoconferencing device, a GPS/mapping system, a movie player, e-book reader, an instant messenger, a digicam and a real-time display for Le Mans racing information and results.
Oh, and here’s some good news for quadriplegics and really kinky gamers: it’s also capable of being operated with only the tongue.
All that in a really tough shell.
