In my experience (having had 5, 2 of them refurbs), the 8700 suffers most from quality control issues, i.e. some of them are wonderful but they aren't all as good as they could/should be.
So if you get a good one (as I have at last), treat it with love. In my book that means protect the screen with Screen Patronus and don't use the OEM holster (the Launcher) for anything but pocketing. (I recommend with the clip removed.) Unlike the 7290, the 8700 doesn't like to be dropped; the odds of breakage are material.
