Welcome to the BB Forums ..... the Search Feature
can be your best friend.
The learning curve shouldnt be hard as you are already a PDA user. I migrated from a basic palm device to my 7100i with no problems. There is plenty of FAQ's & information here in the forums. Just search & read the may threads the longtime power users have put together here.
If you already have everything in outlook, it will be easy to import. On your first Intellisync, just set the option for Outlook to write everything to the BB. Then just normal syncing from there.
