I switched from a 7290 to an 8700c...and i still find myself trying to use the <ESC> key every now and then.

I really like the dedicated phone buttons, and you can hit the red button with the wheel/esc thumb.

Its just muscle memory that you have to change/get used to...hell, I type on a computer anymore, and making periods I hit the shift key and get this >.

its just muscle memory...you'll be fine once youre used to it.
