Honestly it's about time to give up the keyboard. it no longer has the superior feeling. It has the dated and old feeling now. Now don't get me wrong i like the BB keyboard but it's time has come to an end.
If you have tried out the PlayBook yet you will know that the touch keyboard is a very good one. From what I see with OS7 is that it is nearly the QNX OS. And that OS is rock solid.
