The thing that just occurred to me is that very soon most of these devices will not ship with a charger at all, but will sell that as an extra option.

If you’ve got a compatible charger already, then this won’t really be an issue, but if your new device needs 2 amps, and your existing charger only supplies 1 amp, paying the extra $10 (or more, since it’ll be lower volume) for another charger may seem frustrating.

I’m all for standardization. But instead of worrying about a standard charger for a tablet, I think having a standard charger for a laptop. And then maybe standardized batteries and more…

If the consumer electronics industry would standardize interfaces/chargers and other things that are not integral to their business then everyone would benefit. But I guess some people don’t like to work well with others.

I agree with you: there shouldn’t be any distinction. And it could just be Samsung’s approach here – I have no evidence that other tablets will take the same road. In fact, I hope they don’t! ;)

Typical USB ports on computers are hamstrung at a particular current. Larger devices should be able to use the lowest common denominator (PC USB ports), but have the hardware capacity to accept larger currents from special adapters and offer the possibility of quicker charging times where available.

In fact, phones should and do do this — the Palm Pre definitely accepts up to 1A of current and I think the Evo does as well. Of course, it would be better if they could benefit from 2A+ as well.

http://en.wikipedia.org/wiki/Universal_Serial_Bus

In Battery Charging Specification,[36] new powering modes are added to the USB specification. A host or hub Charging Downstream Port can supply a maximum of 1.5 A when communicating at low-bandwidth or full-bandwidth, a maximum of 900 mA when communicating at high-bandwidth, and as much current as the connector will safely handle when no communication is taking place;

These genius alliance have choose USB as a charger cord is a very “smart” guys. Hope they will learn words and characters for reading standards, and will mistakes fewer in future.

And now let’s start to change USB standards for a charging function.
