I do not like docks that connects into the microusb port because well i think it is painful to push the phone into the charging port. the dock i purchased connects to pogo pins.
I do see your point, specially after having a few drinks who wants to struggle with the a micro usb port, ( broke my nexus one's micro usb port while i was drunk and trying to struggle with it last year)
I have to be extra careful with my Atrix and the lapdock cause now i deal with Hdmi and a micro usb port in tandem which is too much work ...lol
