Apple's 'closed' system does appear to have some advantages.
Except for the wallet. E.ON were saying that their app (whatever it does) is more widely used by iPhoners than Androiders. Maybe, as with the iPod, Apple have got the market sewn up again.
I can't imagine what use an E.On app would be, unless it's just to put your meter readings in.
Or to check your bill? I couldn't see much use for it myself, but then I wouldn't, would I? ;D
