I'm a fairly new playbook owner (picked it up during the recent $199 promotion) and a Bold 9780 owner as well. Love both devices, especially the playbook (Bold is locked down by IT policy - not as much fun!).
Welcome aboard. Make sure you check out the playbook and 9780 forums to find all sorts of helpful hints, tips, tricks and troubleshooting help. I know I have found the search function very useful to find what I was looking for. This is a site and very addicting. Cheers
