As a Pixel owner I can confirm that touch on a laptop form factor is somewhat useless. There are precious few times I want to reach out to touch something instead of using the mouse.
The mouse really is a great tool. People need to stop trying to get rid of them.
I (27, UK) was at a hackathon late last year where there were schoolkids (~17). They were all developing on windows 8 laptops, one of them even had a surface, and they all had brand new nokia Windows Phones.
This initially freaked me out until I realised that they were all learning VB at school (shudder), and were just tooling up to use what they already knew. I was encouraged that one of them had had a look at another language (Perl, of all things) and encouraged him to take a look at Python instead; citing xkcd of course.
Anyway, they were all very excited by touchscreen laptops, and actually using them while trying to do development. It was weird.
