Legislation and corporate policies will probably kill camera phones in fairly short order.
A lot of schools are banning them, on top of already restrictive policies regarding students’ use of cell phones.
They’re being banned from places like swimming pools, gyms and locker rooms.
My employer has banned the use of camera phones in all operational areas.
Mix that with the fact that they don’t take terribly good pictures to begin with, and this will probably just be a fad, much like the short-lived video phone systems you could buy at Office Depot just a few years ago.
