Last year's flagship killer just got a killer price cut. That is, if you're willing to live with 2013 or 2014 high end specs. OnePlus One, which took the Android market by surprise, has just announced another price change, but this one promised to be for good. Or at least until the next permanent price cut. It is now $50 cheaper than it was yesterday. But if you pay the original $349 price for the 64 GB model, you also get a year's subscription of Dropbox Premium.
