Many tablets have Bluetooth keyboards that you can connect with the tablet to turn it into a mini laptop of sorts. Belkin is the brand I've used both for the iPad and the Samsung Tablet and they work great.

One charge and I'm good for a week. The case for the iPad one is a little better then the Samsung one, but both are great keyboards.
As for the tablet itself, I found the screen on the iPad easier to read when I was doing more typing, however I prefer the Samsung for document storage and transfer as it isn't as cumbersome. File management seems easier as I don't need an outside app to do it, it has a "My Files" folder where I can store and move around documents much like a normal computer. Also, I think you were one of the ones who mentioned to me about Google Docs and the Samsung Tablet I had came preloaded with links to it and Google Drive and seems to be very Google product friendly.
