That's very impressive on a technical level, although I'm not sure that I agree with the title in regards to the "future of computing." Whilst I am personally in favour of rugged tech that can take a beating, I think a majority prefer looks. On top of that, the idea of everybody carrying around a fully-functioning credit card-sized computer is perhaps out of touch in comparison with cloud computing. This sort of thing will no doubt have a place but perhaps not in the day to day world.

I'm surprised that NoScript for Firefox hasn't had a mention. It blocks a lot of the evils of the internet but I have found that it can break certain pages or sites. To resolve this, it's easy to disable temporarily or for individual sites and I use Ghostery to block any trackers as well.

There seems to be a general consensus that as a website's popularity increases beyond a certain point, the quality of the content begins to diminish. I think that there's some truth in this and I've seen it taken as dogma on Reddit. In my opinion, 4Chan is a good counter-example, despite increasing popularity, I don't think the quality has decreased beyond a significantly aside from people complaining about their "club" that used to feel exclusive becoming more open.
