My dad just got the iPhone 5s and I got him a iPad air, took a while to setup but once it was all his apps, music, emails, browser history... anything he could get on his phone he has on his tablet and visa versa. Also there both usable at the same time. While probably more expensive. Only thing it cant do is swap the screen on the fly but my dad uses one or the other, I don't see moving between the two happening that often to be a concern.
