The Lenovo P780 has a feature I strongly believe would catch on immediately given a wider availability. The P780 can, with appropriate cabling, charge another phone. Who hasn’t has the issue of a colleague that forgot to charge their phone and you end up having to lend them the battery pack or charger you so carefully brought with you? Imagine yourself on Black Friday, lost in one mall or another, and your partner watches their battery indicator dip in the dreaded “red zone.”
The Indian market, the launch market for the P780, is full of hidden hardware gems like this device, and worth watching closely. The phone is available on Amazon for $275 used as of this date, and slightly more for a new model. GSM only, as you might expect, though you do get the bonus of two SIM slots. Very nice.
