I was kind of interested in the keyboard dock at first glance.  Here's a way to turn an iPad into a simple computer that my kid can use for school tasks or email without trashing my desktop computer setup.<p>But on second glance: how do you drive the UI from the keyboard?  Can you use a mouse?  Are you going to have to lift your arms and gesture all over the place to open a file, change apps, etc?<p>If they have an answer to the second problem, watch this thing get pushed heavily at the education market in the fall.
