I have been a longtime practitioner of doing GTD on the Palm. Since it is time to get a new phone, I decided that I would get a Palm OS smartphone with e-mail capability enbled. The problem is that Palm only appears to offer three Palm OS smartphones, and my carrier of choice (AT&T) only carries one-- the Centro (which I hate because of the small size). If I want to stay with AT&T and go Palm (non-Centro!) my only option is to buy an "unlocked" Palm Treo 680. I'm mulling that option at the moment, but considering other solutions.
Today, while I was talking to DAC ustomer service, I mentioned that the last time I heard, David was using a Treo 700p. I was astounded to hear this person tell me that they believe David has switched over to the Blackberry. Wow! that's a paradigm shift...I'd love to hear David discuss how he is implementing GTD in Blackberry if this is true.
I'm currently considering Blackberry, the iPhone (with OmniFocus), and the Palm.
Just to make things more complicated, I am also mulling a potential move from a Windows environment on my laptop to the Mac OS.
Although I realize that I must make the final decision, I'd love to hear input from the forum on the relative pluses and minuses of the various tools.
