Well, the lack of a keyboard and mouse and the lack of an intuitive way to solve these problems in a mobile device. These comments seem to imply that I can add hardware and the problem is solved. If I add hardware, I no longer have mobile on the go development, I have a bag of crap that makes this less convenient than an air or ultrabook. Now if someone invents a way that eliminates the need for the keyboard, then I'll use it with glee. But this product is a desktop app on a mobile device and does nothing to really innovate in the space. I want this to work, but it isn't as simple as writing a desktop app on android.
