I think you will see a lot of countries with carriers who adopt to the microSIM as the iPhone 4 and iPad continue to grow. I would imagine that other manufactures are not far behind as well with phones of their own. It takes a big market mover like Apple to really push out a new technology like this. It gives a foundation to microSIM when a manufacturer will sell 10s of millions of a single device in a year without a threat of retreating the next month and releasing a new device with a regular SIM.
