iPad vs galaxy

[BART]

So I bought an iPad, which I have 14 days to decide if I want to keep. The other device I've looked at is the samsung galaxy, but unfortunately, I know nothing about the android OS. The price is the same, and so far the iPad seems like an oversized iPhone. I've read the reviews online but they never seem to be very "real world". Is the android OS more like a computer? Meaning, would I be able to store data and files on it like a laptop? What are some other features android offers that I may be missing on the iPad? All feedback is welcome, thanks in advance.
