I think android tablets will have a problem of having non-standard interfaces. There are already point of sale machines using the iphone because all iphones have the exact same bottom connector so it makes it fairly standard to interface across. All android devices have different ways of hooking up to -- I don't know why device manufacturers always like reinventing the wheel when it comes to hardware interfaces. I already own a few dozen different phone chargers at home, the only one that hasn't changed is the iphone.
