My Sony Digicam has a proprietary port that needs an adapter to connect to a standard USB port. The battery can't be charged via USB but has to be taken out of the device and plugged into a separate charger. And, of course, the photos are stored on a crappy flash card format that nobody but Sony uses. All of this sucks a** but I can live with it. So I'm sure the extra USB adapter for the iPad won't kill me either.
Clearly, this is a bug rather than a feature, but there are simply no perfect gadgets in the world. Every gadget has its own shortcomings and compromises. To me, the iPad has the least shortcomings and the most to offer, so I'm buying it.
