I'm trying to decide between the Key2 and the Motion. The last keyboard phone I had was the bold, then went to the Z10 and currently the Priv. I like the Motion but worried it may be too outdated already with the Key2 having more RAM, better camera, and faster processor. Then the Key2 has a funky screen shape and not sure if I can get used to the keyboard again. Any suggestions?? Am I missing any other key differences?
