I respect the heck out of HTC for it's past with MS Windows Mobile and as an original WP handset maker. I love the feel of an HTC phone- it just FEELS like a real piece of equipment. I would love to see a new WP 8.1 hit the market with the ONE hardware.
But, until I see HTC truly support their devices- Android or WP- I would take a Nokia, Samsung, or any other option prior to it. My time with HTC products tell me this company just does not have the resources to support it's devices. From the Thunderbolt flop and the EVO 3D slug, to the Titan call/audio problems and Titan 2 multimedia faults my wife and I dealt with, to the fact Samsung has twice as many options in it's WP Hub VS. HTC's, and I need to see a couple years of proof HTC will support it's customers.
Do that, and I would happily jump back on HTC. Excellent hardware.
