Using Modernizr to test for tablet and mobile - Opinions wanted

Question

I want to use Modernizr to detect whether a user is view a site on a desktop, tablet or mobile device.

My initial first thoughts are obviously to check screen sizes

This question is a bit old but I couldn't find a better answer when I googled it.

The best way to detect them is by screen size.

With Modernizr you can use if (Modernizr.mq('only all and (max-width: 480px)')) { ...}
