Hi I want a tablet for mainly watching Full HD movies and anime.I have searched for the best and found Nexus 10.I have read about ram problem.But I don't care about it because I want it only for watching.So I would like to ask: are there heat problems? especially when I use it for long period like 7 hours? Do it has google play? what about the storage?I heard that I can't have sd card for it.but I can use hdd with it. is that true? And is there any problems that can affect watching?
