HTC had launched the HTC One (M8) for Windows last year, a Windows version of their then current Android flagship. When asked about a Windows edition of the latest HTC One M9 +, Chia-Lin Chang, President of Global Sales and Chief Financial Officer at HTC, said that the company is closely working with Microsoft as they ramp up towards the release of Windows 10.
But that mediocre camera though. They added more megapixels but the outcome isn't as nice as the ultrapixel cam they had.
If that's a software issue then count me in. Not that I hate Nokia/Microsoft but once I heard the audio on the M7, I was blown away. Best phone for audiophiles ever.
