Basically, I'm trying to figure out which one to buy, and I want to know if I can: 1) type in my windows documents from my computer on a toshiba or samsung 7" tablet? 2) work/type in my power point presentations and hook by tablet into my projector and present my powerpoint presentations? 3) I'm guessing I can hook either up to an external keyboard and type. 4) I also want to read books with either one. Can I read both kindle and nook books? I guess I want to use it to replace a laptop computer. Can they do that? Thank you in advance.
