Like many of you, I use my PDA to handle quick e-mail and calendar reference when I am mobile and my laptop is otherwise inaccessible. Having my e-mail and calendar updates wirelessly pushed to me has been invaluable. I agree with David, that processing email is [currently] usually best done at the computer, but it should not have to be that way.
It is time for vendors to provide adequate tools so that we can process our information where we are. There's simply no excuse for not having categories or folders that sync back to the desktop. Why do some tools still make action management on a mobile device so difficult? Because they still don't get it. Until they do, or until someone comes out with a better solution, we will still be here, discussing work-arounds.
Inspired by people's comments and questions about processing email on a wireless device, I've posted my own $.02 on processing wireless e-mail on my blog.My measure of success in evaluating a new technology or productivity tool is the degree to which it becomes transparent to the actual work being done, and the level of productivity that is gained as a result. A doctor should not have to think about his scalpel or stethoscope; neither should a writer have to think about his pen or legal pad.
In the same way, a knowledge worker should not have to think about his information processing tools. Any time he does, he robs himself of the opportunity to get his real work done.
I would like to know what you think. Maybe some of the developers and manufacturers are lurking in this forum and would care to respond directly.
