I'm truly sick of hearing that the phone is the only device that matters. I use my phone very, very sparingly, and only when I'm away from my laptop. A phone isn't the nicest device for consuming the web, and I doubt it's even the most popular.

‘Only’: OC hasn’t said exactly that -- he talked about authentification; most people don’t really say that either. Many journalists exagerate a trend and slight majority, but I would (tongue-in-cheek) blame you first for reading badly written magazines.
