Web apps are starting to get more and more impressive recently. I've started using Forecast.io as my main weather app and I honestly can't tell it's not native. This is the first good game I've seen though, but it's encouraging. Anyone know why web apps are getting so good lately? Hardware power, browser optimisations, or what? Looks like there's a bright future ahead anyway.
