This isn't specific to just one Surface line, but the Touch cover 1 is probably the poorest out of all four extant keyboards. The Type 1 and Type 2 have moving keys, and for school with a lot of typing, those are highly recommended. Touch 2, however, is also very much improved over Touch 1. So between Touch 2 and either Type 1/2, your choice is going to be dependent on feel (moving keys vs. none) and just how much typing you intend to do. That said, some people will still like the Touch 2 even for more typing than "occasional." If at all possible, the best thing to do is try to find them in-store to try out (MS store especially).
