Nah! I have used Windows Phones keyboards for quite a few years. None of them were so hard to negotiate as the L5’s keyboard. Of course autocorrection makes a difference, but the L5’s keys are somehow smaller or at least more fiddly then the keys I was used to on my previous phones.
O, and in landscape orientation the keyboard takes up the whole screen. That makes typing a lot easier, for sure. But as you can’t see what you are typing, you still end up with loads or errors.
So, the keyboard is too small in portrait rotation, and to big in landscape orientation.
