I've got a slightly eaarlier version Archos - the Internet Tablet 5. It does what it says on the tin
500GB storage means you are never going to run out of stuff to watch, and it's a plenty big enough screen to view when your crammed into that aircraft seat, whilst still being able to fit in your pocket. Battery life does not get to the 7 hours video claimed even with the add on battery thing that is supposed to give 1.5 times the lifespan. Once I'd paid the extra for the add on codecs, I've not had a problem with playback of any content that I've acquired. Perhaps the only thing missing was the 3G support, but then most places you stay these days have wi-fi, so why do I need more mobility?
Personally, I want want of these things to have a decent level of storage for media. Most of these tablets are just not going to be big enough.
