Have one too & agree about the texting....used to text as I was dashing from one place to another, but you can;t really text on the move as the touchpad is rather sensitive & constantly hit the wrong letter.
Another (mini) bug-bear is the persons number doesn't come up when you are texting - I've sorted it now by ammending each name to include "mb", "hm" or "wk".
Finally, I have a bit of an issue when I'm trying to set appointment - not surre why, but sometimes they don't seem to want to "set up".
Mine wasn't too dear as I had a good upgrade package, but will probably downgrade again next year - guess I'm not as high tech as I thought!!
