Nope, but they look a bit special. I have a PDA called a "Tapwave Zodiac 2" which does much the same type of thing as this little beauty, but not quite as well. I use it mainly for TomTom navigator sat nav, but I also use it to play DIVX movies (it plays native DIVX/XVID/MPEG4 without any conversion or loss of quality), MP3's and for the excellent Mame32 emulator for the zodiac. I also use the amiga emulator on it.
So if your GP2X is better than the zodiac (which by all accounts it most certainly is), you'll be well happy.
