I personally don't buy high end products like the iPhone or Surface. I have used them for work, and pound for pound, I still prefer my Cyanogenmod OnePlus 2 and Chromebook running Debian. I get easily 8+ hours of heavy use out of each (12+ for my chromebook) and I have a far greater level of control over my data. If you look at some of the things coming out of Shenzhen lately they are hitting price points that allow almost everyone to own a relatively high end phone or computer (Remember this is what Microsoft used to be all about, they cut the cost of a PC to a third of what it was before them). That's what innovation looks like to me. Not some feature you will forget about a week after you have the device.
