I enjoyed a lovely week off last week without a phone or a computer. But I did have my iPad, and I shared it with the kids. As I watched them, I realized that the 9.7-inch screen, which can detect 11 finger touches at the same time, is great for multiple players using the same iPad to play a game. Call it three-handed gaming. One of the games we played together was PopCap Games’ iPad version of Plants vs. Zombies, which has been huge hit.
