The OLPC's Activity metaphor is basically taking over and, having always loathed desktops and never understood why my computer must simulate a desktop (with all the clutter that implies), I like it.

It's not just GNOME: iPhone, iPad, and Android apps are at their heart the same as activities (the Android API even uses com.android.Activity as the base class for Android apps).

Yes, it struck me that this looks like a desktop version of Android...obviously tweaked to take advantage of the extremely larger screen and available resources.
