why still that obsession with removable batteries? Powerpacks are dirty cheap. And I actually don't have to switch of the phone. And they are small enough so I can easily charge in a back pack or some bigger pocket. Also, modern batteries last longer then the phone itself. And most of them can be replaced when needed. Not by average Joe but....
And lack of micro USB...... Isn't it mandatory within EU? Or at least they should provide some adapter.
