"but you can't do any real work on them."
Oh dear - not that old objection. Yes you can.
Just in case you think I'm guessing my wife got a contract to write her second book from a publisher and fulfilled that contract on an iPad. If that's not creative "real" work then I don't know what is.
Yes - video editing is probably best left to beefier devices, but most "real" work can be handled by a tablet. You may want to consider the opportunities presented by bluetooth.
