I recently tried to "upgrade" to an 8320 from a Pearl. Just couldn't do it! I gave it two weeks. I have a long history of using SureType and the full qwerty just wasn't working well for me.... The keys are smaller and are spaced which may have something to do with it. I really wanted the bigger screen but in the end it just wasn't worth the hassle. Now, I'll just wait for something to come along that makes the hassle of reteaching myself worth it!
