Uh, you answered your own question with:
Along with blinkfeed, duo camera, ultrapixel camera, 5mp front facing camera for selfies (like it or not, it would be used a lot) aside from the Sense-specific features.... they have a pretty solid feature-set. The metallic build is just another one of those features.
Uh....they did do that. They have an extreme power saving mode that will let the phone last an extra 15 hours when it's down to 5% battery life.
Have you even seen the feature set of the One? Sounds like a really uninformed post.
The only decent selling points this phone has:
1. The Slippery Metal Build, which some prefer the looks of
2. The 5MP FFC.
Everything else is matched or exceeded by the S5, and the Build Quality is highly personal so we cannot say for a fact that is an objective advantage (it has some serious disadvantages as well).
BlinkFeed exists. So does My Magazine, which does basically the same thing.
The only thing Innovative about UltraPixels was the name. Cause it wasn't all that innovative. They just put a larger sensor with larger pixels and lower resolution in the device and gave it a cute moniker. Samsung's ISOCELL tech is innovative. UltraPixels were not innovative.
Duo Camera doesn't accomplish anything you can't do on a Samsung device with one camera sensor.
Samsung has more software features than Sense, including "Solid" features. They have more, better, and more innovative hardware (and hardware capabilities, like 4K recording - you can't do that with a 4.1MP camera sensor) in their devices.
This HTC One is the most 'S' release of all the flagship refreshes we've seen thus far. There is less reason to move to this phone from the One than to the S5 from the S4. What an underwhelming device.
