One handed soft keyboard

Interesting idea Microsoft Research, and I like the thought process

Two things that strike me initially ....

1. It takes up a lot of screen space replying to texts and emails where you have to check what has already been said might be difficult... but if you are just typing something off the top of your head that's not going to be a problem
2. It's at an angle if you look at what you type while you are typing you have two things to look at that both require different perspectives

You can read a little bit more about the keyboard at Gizmodo and The Verge the images have been leaked from a presentation and published online by WMPowerUser.com
