But how many mobile devices are actually doing something useful on the web? I end up going to a PC if I'm going to purchase stuff off of Amazon for example. I may occasionally read some news through my phone, but I try not too because of the small font. Tablets? If every website didn't switch to a damn mobile phone style format on a 10-12" tablet, I might find it useful. I have to click a button to "Request the desktop version". I don't think they're replacing desktop PC's yet, for now, they just compliment my PC when I don't want to lug around my laptop.
And then we have all the bots on android devices, not even google knows how many there are.
