He isn't trying to convince anyone, he's staying objective.

Just for you I'll translate that wall of text, basically he's saying:
Smartphones arent smartphones anymore, they are superphones.

He's saying that yesteryear there was an advantage of having a full desktop PC in your pocket, but now the hardware has gone far enough for the software to catch up. Now mobile Apps are powerful enough to compete with desktop ones, surely there's a few compromises but its true nonetheless. And that comparing those powerful mobile Apps, the experience, to a desktop App that's squeezed into a mobile device as tiny as the 3.5" N900 is laughable.

I tend to agree, there is a shift occurring. Maybe not fast enough, but the iPad, NOTE, Transformer and WinRT are evolving computing. The PC has already shifted from large servers into big desktop boxes before, and then to a laptop and then to even smaller, lighter, thinner yet more powerful laptops. Now its going to get more personal, tablets do look like the new future. Call it the Post-PC or PC+ era, call it whatever you like, but phones like the iPhone 3GS, SGS2, N900 are beginning to become obsolete, despite how ridiculous that sounds.
