Hugh,
First go apologize to your family for all future transgressions that the CrackBerry will precipitate.
I've had one for over 3 years now, all of a sudden I had to own one for work... I just got the new Blackberry Pearl, like it much better than the others because it's smaller. I always hated the std. BB because i felt like I was talking into a calculator...
Anyway a few cool things:
1. With the serial cable you can use the BB with your PC to dial-out to the internet anywhere.
2. Google Maps Mobile works with the GPS (if enabled) and it works really well. Free portable GPS.
