My 13" Macbook Air and iPad (Gen 1, 2, and 3) haven't been more than 35' away from me in two+ years except when I'm (A) Showering, or (B) going to the washroom.

My 13" Macbook Air and iPad (Gen 1, 2, and 3) haven't been more than 35' away from me in two+ years except when I'm (A) Showering, or (B) going to the washroom. (And actually, because my shower is within 35' of my bed and gym locker, we can even eliminate that exception) So, you don't have to convince me of the utility of each, and where they are optimized. But, I would so love to just have one sub 16 ounce gadget to carry around with me, with some amazingly easy to manage keyboard/touchpad (with a bunch of USB3.x ports) when I need it. It would also make keeping my video/song files a lot easier to keep synced. Switch to OS/X when I've got the keyboard attached, and switch back to IOS when I don't. Or something. I don't know. But I really only want to carry / charge a single device.
