HTC One has impressed many people starting from its unique design, that creates an illusion of a bigger screens than it owns: a 4.7 inches Super LCD 3. Also, one of the last generation CPU, Snapdragon 600 quad-core 1.7Ghz, got the attention of the world, and its 2GB of RAM brings it on the top of the best smartphones of the year!
One disputable subject is its rear foto/video camera that have only 4Mpx. Yeah, at the beginning I was shocked that this devices has a so poor in Mpx camera, but after a shortly research I found that HTC One has a special camera that uses the "UltraPixel" technology to get higher performances, even in low lightening areas. In fact this technology uses more pixels on the same area photo sensor that standard cameras, to capture more efficient the light and to get superior images.
Another detail that has impressed the world is that the minimum internal memory storage is 32GB. Well... friends, it's a big step made on the smartphones' storage market, and until now it's the first mobile device that offer so huge space as memory.
Also, the battery that joins it is enough but not for everybody if we take in consideration that 2300 mAh isn't sufficient for a person that could use an internet connection for hours in day to day activities. But don't worry to much, because you can get an extended battery.
