So, I've been around PDAs and PDA phones for a while now - dating all the way back to the old school monochrome Palm Pilots...graduating to Dell Axim, and then moving on to a Torq and to my current HTC Touch (what a leap). By and large, I'm familiar with their interworkings and have been active in adding 3rd part apps, as well as some minor registry tweaks/hacks.
Coming over to the Blackberry world, I'm wondering (from past Windows Mobile users) what I should know about the differences, if anything?
What software is worth upgrading through 3rd party for most people, and any other tips/tricks you might want to throw out there?
I've got nothing else to think about, currently, since we're still all dreaming of the Storm release.
