I'm not a texting teen ;)
Let me explain it this way: The push-technology is very popular, this is why many makers implement it into their mobiles - in addition to the regular POP3/IMAP support. That way consumers, especially regular consumers (which the Pearl is aimed at too, as I understand) and business consumers without a dire need for push (they still exist) enjoy more options.
Or lets say had RIM bothered to implement POP3/IMAP support, I would not have returned the phone in disgust, and who knows, maybe in a while had developed a need for push too. It felt crippled / came with plenty strings attached, so it had to go. Of course, if you *are* after the push service, it is a pretty neat little device, mainly because of the most impressive text recognition, trackball control and other decent business oriented functions. Yet as I said, the overall execution could be more solid, it feels a little shoddy. If you can forgo the superb predictive text, there are many non-RIM phones of better quality available which also offer push.
