Featurephones, dumbphones, "messaging phones." No matter what you call them, it's clear that these devices are quickly being replaced by cheap smartphones at the low end of the cellphone market. We've seen devices like the LG Lucid and the HTC One V, or the Sony Xperia U in the UK, all of which bring lower specs and weakened performance, but still offer all (or at least most) of a smartphone's connectivity and functionality.

That's precisely what T-Mobile's latest MyTouch and MyTouch Q purport to be. The new devices are $49.99 with a two-year contract, a price historically reserved for phones with nine keys, a clamshell body, and no internet connection. Their spec sheets are lackluster, at least compared to T-Mobile's more expensive smartphones: 1.4GHz single-core processors, 5-megapixel cameras, and 4-inch 800 x 480 displays. (The only difference between the models is that the Q has a slide-out QWERTY keyboard at the cost of thickness, while the basic MyTouch doesn't.) But they should be a huge improvement for first-time smartphone buyers.

The entry-level smartphone is very much here. But what's the cost of saving $150 over T-Mobile's high-end handsets? And is it worth it? Let's see.
