I could attest to some of the stuff this guy says. In a certain southeast-asian country, everyone is using Blackberries not because they're cool but because unlimited text-messaging plans makes them really cheap.
If you travel in more than just...ahem...Indonesia(I'm presuming), you'll notice they are "everywhere" in multiple SE Asian countries. As Nokia reigned supreme from the 90's until just a few years ago, Blackberry has become the new dumb smartphone with their Edge(or equivalent) network support. It will be a long time before most of the world is on a 4G equivalent. RIM will do fine for quite some time.
