Okay, after reading another excellent blog post by Tomi Ahonen, I realized why push email and the Blackberry are so popular in North America: they're using it as a replacement for SMS, which they still haven't understood. I'd heard of how the American operators had sabotaged SMS, but I thought those problems had been sorted out and SMS had caught on like it has here by now. It seems it hasn't, although the service actually works now.
But there's no reason for me to keep going on about this. Read Tomi's post, it has lots of interesting info.
