[Hope this works] I posted a message about my experiences converting from Palm Centro to Droid at the address I hope appears below. If the link doesn't appear, my thoughts are in the Droid Tips and Tricks forum under the topic "Sync Outlook Contacts & Calendar to Google."
I may take some advice from the rest of you about Notes, though. Google Docs doesn't seem to let me edit on the Droid, which is a bummer. And I'm not crazy about having to use muliple products on my PC just to get at the four core apps (Calendar, Notes, Tasks, Contacts).
It certainly isn't a mature PDA yet. But it's awfully cute.
