I have just made an impulse purchase. I decided that I'd like to have something to play with on my flight to New York next week so I ordered a gpx2. From the site:

What's in the box?

240Mhz GP2X Console MK2 (Latest version)
4 Rechargable Batteries
GP2X Pouch, Hand Strap & Headphones
USB Cable for PC connection (With 2.0 Support)
Preloaded Linux with Media player (MP3, Divx, Xvid etc.)
CD with Games, Utilities, MP3 player, Movie player
Firmware 3.0 (with 5 bundled games)
SDK - Make your own games!
Full User Manual
How to Guide/ Movie Samples/ Game Ports included

The GPX2 is a linux based handheld console that supports a wide range of emulators. I plan to fill an SD card with Sega and Nintendo classics as well as a good measure of Lucasarts adventures and relive my youth in British Airways luxury!
