I traded in my treo for a BB last summer. I still miss the touchscreen... sigh... but the BB is a superior device. A couple of months ago I had to switch carriers and the opportunity arose to go back to palm. I didn't have to think very hard...
Welcome! I ditched the Treo as well and went with the Curve. While I do not miss my carrier, I do miss the touchscreen still and the knowledge that I had on the palm OS.
However, I don't think I'd go back, Palm just rolled over when they could have been great. Rim is where it's at, for me at least. Hooked.
