Well except the touch screen!

I've owned several Nokia phones (and I was very happy) but this is my first smartphone, so Microsoft.
Bought for a double with 2 sim-quality camera, on these points there, that's ok. There are enough apps (free) to download on the store for my use. Microsoft Office Online is integrated original, the home screen is customizable in every way, the sound is good. It is possible to put an SD card up to 125 GB.
By cons, some functions lack of ergonomics, eg inability to set homepage shortcuts certain "parameters" or alarm programming or tasks.
And as indicated on many forums, there is a problem with the touchscreen. I installed the update Denim (Windows 8.1), which improves the situation somewhat but it is still not the top. Typing on the keyboard is sometimes unpredictable for sms, unlocking the screen too. The keyboard is too sensitive sometimes, sometimes not quite following the area is pressed (for example, several characters can be displayed by pressing a single key, or a menu function is above or below ... )
100 short months, I am still quite satisfied, I only hope that Microsoft will offer an effective new SHIFT to the touch.
