Hi All. I am new to tablets so not that clued up on things. I have purchased 2 already and had to be returned as they do not fit my needs to replace my old Archos 605. The main reason I will use a tablet is for watching videos and I mainly have files in mp4 format off eztv.it which my Archos no doesn't support. The 2 I have had already dont play these videos despite saying they support mp4. I have about £70ish to pay and want something with built in some memory (with room in increase with a card) and decentish battery life and preferably no more than 7" screen. Any ideas? Cheers for the help.
