Future iPads might get Surface-style keyboard covers, hint insiders30
An ex-Apple employee posted on his blog that word with former colleagues hinted at a Bluetooth-enabled keyboard cover prototype being prepped for the iPad franchise. Now whether this accessory will see the light of day tomorrow, for the new iPad 5 and iPad mini 2, or at a later date, or at all, is mystery, as far as Apple's prototypes are concerned.
If it does, though, it will likely replace two of the current ones - the magnetic iPad cover and the Bluetooth keyboard. If the new keyboard cover sports Bluetooth 4.0 LE, then even better, as that will allow to not worry about endurance for about as long as you'll be realistically using your iPad.
