Has anyone found a big, stable third-party charging dock, with a socket for the entire bottom edge of an iPad? So that someone with limited movement and eyesight wouldnt have to try very hard to get the connector lined up right? Ive seen a few speaker docks like this, but theyre expensive and overkill and bulky. (Speakers would OK if the dock is still sub-$60 and doesnt make the unit too huge.) The main thing is super-easy insertion so the dock connector is always lined up. Apples iPhone and iPod docks have been that way... but not their iPad docks. TIA!
