So today the Pope lit a virtual Christmas tree (made up of actual lights, but no tree), using an Android Tablet to light up a mountainside over the town of Gubbio (remember the story of St. Francis and the wolf? That Gubbio.)
Geeks everywhere interpreted the gesture as an ecumenical outreach: after all, he had previously used an iPad to launch the Vatican news portal. Although Benedict prefers the pen to the pixel himself, the head of the Pontifical Council for Social Communications says "With this Pope, Vatican communications have made enormous strides."
Go here to read the Pope's comments as he flipped the switch (er, touched the icon) to light the tree.
