Not all cell phone stores use live models. Most stores put dummy phones on display: same shell but no guts; fake phones.
Fake is cheaper, but Best Buy Mobile displays live demos of the most popular phones.
And the public paws the crap out of them.
That’s why they’re good test subjects, all lined up in a row, handled and mauled all day long. If there’s going to be a weak spot on the phone, you’re going to see it.
(ever seen Motorola’s stab proof phone?)
