I am looking for a tablet with android system and want to buy one for my study. But my budget is a little tight since I'm still a student now. I had a look on the Internet and found 2 android tablets, they are http://www.tinydeal.com/google-android-7-touch-screen-wifi-tablet-pc-px8j81-lm032g05-p-6320.html and http://www.tinydeal.com/google-android-7-touch-screen-wifi-tablet-pc-px8j81-l7012g03-p-7684.html I think the first one is a little like iPad, maybe is it a copy? Which one would be better and more pratical? Will it be a good choice to choose such a tablet? Could you offer me some professional advice? Thanks in advance.
