For the busy professional running from meeting to meeting, this could certainly be handy. This is a nice piece of innovation from Palm. In fact, I am surprised that solutions and/or services such as this haven't been made widely available already to other smartphone platforms.
But better than that, it does stuff for you. So when you wake up in the morning, it has taken your calendar -- if you ask it to -- and downloaded the maps for your whole day, it's downloaded the wikipedias for the people you're going to visit and the companies you're going to see... Why is it on PCs you have to go and do all that? And when you're late -- get this -- when you're late it -- remember, this things has GPS, it has a clock, and it has your calendar. So it not only knows where you are, it knows where you're supposed to be and when; and so when it realizes you're going to be late, it says "Hey, not only are you going to be late, but I can take care of it for you. I'll send an e-mail to your assistant or to the people in the meeting, which would you prefer? And oh, by the way, here's the map." This is the beginning of a new wave.
The key is tying all the pieces together. I've had my calendar remind me plenty of times when a meeting was about to start. For the phone to know where that meeting is, see that I am not in the right spot, and take corrective action is exceptional.
McNamee does say "if you ask it to," which means this type of functionality can be turned on or off, thankfully. That's a good thing for the employee who values their privacy. McNamee didn't expand much on what other features are brought together in this synergy between applications.
