Tossing the Treo 755 for a Blackberry

I have had a Palm powered Treo for years... Currently I have the 755p and I have had 3 replacements so far. Palm powered Treo's have always had bugs but living with them was worth it for their advanced features. Now that other phones have caught up and surpassed in functionality its time to chuck it and go with something else. Today I am going to try the Blackberry Worldphone. I know what most of you are thinking... why not the iPhone? Well 2 main reasons:

1) Bad ATT coverage and lack of 3G towers in Nebraska. - Every time my friends come visit they say the coverage on there phone sucks here. 2) I am not into touch screens and like having buttons for the keyboard.

So why the Blackberry Worldphone? Well our Sprint rep Heather said she can give me a replacement BlackBerry World Phone for now. Otherwise its like $500. I am going to try to get used to the blackberry OS and then will probably end up getting the curve or the BlackBerry Bold when it comes out in a few months. So in talking to my friends it seems those who went from a Blackberry to the iPhone are not back with their Blackberry's. Those who went from a Treo to a iPhone are still with the iPhone. Are you one of these and which way did you go if so?
