Aesthetics aside…
It seems like the iPad’s keyboard, in landscape mode, leaves you no choice but to hold the device in one hand and hunt-n-peck with the other. What if the keyboard was split into two, and placed in the lower-right and left corners? Then, you could hold it with both hands, and type a la the iPhone.
It’d be a sacrifice to the key size, for sure, but it might be more comfortable and functional.
You make a very good point. I was thinking the same thing. The other option is balancing it on your lap while you try to type. Thankfully it supports Bluetooth and the Apple Wireless Keyboard. That is how I plan on using it when I get one.
