Got this a couple of days ago, and I am very impressed.
The battery life seems very good. You get about what is clamed. Been on you tube and the streaming was smooth. Connecting to the internet is very easy. And also the touch screen is very responsive. Tried a couple of cheaper makes, and they were rubbish. Its worth paying that little more to get something that you wont get frustrated with! On the gripe side, you dont get a micro usb to full usb adapter included. Which is a little stingy but you can pick on up for 2-3 pounds on Play. The speaker is a little weedy, and its on the back. This is no surprise really for something that is only about 11mm thick. (But it does power my full size head phones a treat). Also they leave out a couple of frequently used codecs. So you have to go to the Archos shop to buy them ( Shame on Archos ! ). But once you do it works very well with almost everything Ive thrown at it. Downloaded a third party player and it was poo! So it was worth it. All in all I am well pleased with my (half the price) I Pad rival.
P.S This a G9 model. Dont know why they list it as a GP. Dont even think there is such a thing?
Here is an update, having had this for about six weeks now.
Still very pleased with it but it does have its quirks. Now and again it will freeze, usually when trying to load a few videos off youtube before the others had finished. Or say something has unexpectedly stopped for no apparent reason ? But then again who hasnt had anything thats computerised and it hasnt come up with that sort of message ? Got a hdmi lead for it and it can be very temperamental with that. So now you know. All in all still pleased with it. But dont forget it is a computer so its never going to be perfect !
P.S If you look on the app market there are some other good video players to download, but the one that comes with it is pretty slick. And also you can plug usb drives into the 3g connection on the back just make sure you turn it on in settings.
OK here is the final update. Had it or about 16 months now, and its feeling a bit flimsey and it takes me about an hour of turning it on and off and going in and out of system recover mode to get the screen to sense any touch. So its going in the bin this is the last straw. P.s I am writing this update on my much better (up to now) Toshiba AT300SE which now is even cheaper than I paid for the Archos
