Cellphone market needs a shake-up

[Commentary] Motorola, which is still owned by Google but about to become part of PC maker Lenovo, is changing the equation. A few months ago, it introduced the unlocked Moto G Android phone for $180 and last week, it introduced the Moto E, which sells for $129 unlocked and without a contract. I'm hoping that other companies will follow Motorola's lead by introducing high-quality phones for under $200 without a contract. Personally, I'm tired of being locked into a long-term relationship with my cellphone carrier.
