Since the battery capacity is similar or in some cases even larger than the one in MacBooks - why not use the more powerful chargers and a MagSafe connector? Imagine charging your MacBook Pro with a tiny dock connector, where you could practically charge it only when shut off. Otherwise it would just keep discharging or in the best scenario - keep at the same battery level. Nobody would buy that kind of laptop. Nobody would even suggest - as they do with iPad - "Hey, just charge it overnight!". After the introduction of wireless sync I was almost certain that the obsolete dock connector (still no USB 3.0?!) would be simply phased out. Let's be honest - MagSafe is an ideal way to charge a portable unit. No force needed, it just snaps on. Hell, they even made a SmartCover in the same fashion. Just not the charger... But then again... there is always iPad 4. Sorry... iPad - early 2013.
