After a short delay, the HTC One M9 is finally launching on March 21 (in Taiwan)
Only the One M9 32 GB will be available starting March 21 (for around $693), while the 64 GB model should be released on March 27 (costing about $756). After Taiwan, the HTC One M9 will be launched in many other markets around the world. The handset will arrive in the US on April 10, and all major carriers are going to sell it.
While it doesn't look too different from the One M8 (at least not when viewed from the front), the HTC One M9 comes with significant improvements over the old flagship, including a 20 MP rear camera, Qualcomm's octa-core Snapdragon 810 processor, and a 2840 mAh battery.
