Laying the iPad flat in landscape orientation makes typing on its touchscreen relatively easy once you get used to it, but what about typing when you're holding it in your hands? If you've got hands like a basketball player, thumb-typing on the iPad in portrait orientation probably hasn't been a problem for you so far. For the rest of us, we were hoping for a better solution. In iOS 5, that solution is here: Apple calls it the split keyboard, and it's pretty awesome.
The old button to show/hide the keyboard has gained a few more options. Tapping and holding the button will bring up options to Undock or Split the keyboard, as shown below.
