Greetings! I was a pretty faithful Palm user for a few years. I had a Treo 650 and then a Centro.
The Treo lasted quite a while and then just kept resetting itself and then stopped turning on altogether. The keyboard started going first though. My "o" and "p" just wouldn't type. It was the strangest thing. I chalked it up to age and figured this kind of technology just doesn't last more than a couple of years and I moved to a Centro. It was okay, but I just crashed the email. I'm a very heavy email user, so it just kind of puked one day.
So, I just ordered my first Blackberry. An 8330 Curve from Sprint!
