None of the above.
What I want is a mid-range WP smartphone with a sub-$300 "all-in" price. As in, the price to buy outright.
Sell it for $299 on EVERY carrier under the sun. The Big Four, MetroPCS, Cricket, US Cellular, you name 'em.
It would be the Commodore 64 of smartphones -- the first mobile smart device "for the masses, not the classes." It wouldn't require pricing games with "$199 up front plus a two-year contract on an inflated price plan with an eye-watering ETF."
Just pay for the phone, choose your service provider, and go.
