Me, taking the piss out of iPad 3 speculation that gets entire articles out of analysing an invitation:

If you look at the launch invitation the Calendar app icon is nice and clear and Retina-y, but just look at the Keynote icon to the right. It’s so blurry you can barely make it out.

It’s clear what Apple’s doing here: because its Retina display is so powerful and awesome and amazing, it probably uses quite a lot of battery power. Apple’s solution? Make the bits you aren’t looking at go blurry to save pixels. Thinking like this is why Android can never win.

In the comments:

so its not just out of focus, apple has invented a display that knows where you are looking?

Muppetry.
