Those who have been waiting for HTC's latest and greatest need not wait much longer. The OEM has just announced today when their existing fans and new converts in the US will be able to grab the One M9 from their favorite carrier or retailer. Starting March 27, at exactly 12:01 a.m. ET, people can order HTC's 2015 flagship online. But if you prefer to buy it from a store, you'll have to wait for April 10 to roll around before you can do so.
