If you will have a decent laptop anyway maybe there are not any reasons to buy a tablet.

But in case you want something like a mix, an ultrabook / tablet you can check devices like the Vaio Duo 11 / 13, Vaio Tap 11 or Surface Pro. I have the Duo 11 and can't be happier with it. It was exactly what I was looking for. Sony has sold Vaio division so stores have deals on these devices.
