I LOVE MY ARCHOS IT!!!!!! I've had it for almost a year now. Its the only media player with 3D graphics accelerator and open GL. the only thing I would like to see on it is the FroYo android 2.2 will not likely come out on the 7gen. :(:( they just released the 8th gen with even better hardware so if your going to get one wait abit and get the 8th gen. I originally got it with the intention using it as a portable wifi sniffer, wireshark for android. but I couldn't any good software for it. and by that time I fell in love with the archos media player software and the specialized graphics. If I root it then I loose the software that take advantage of the acceleration :(:( or if you want a cheap one the prices on gen 7 are dropping.
this is the one I have Archos 5 IT
