Online training or seminars for Apple stuff
Did you know that Apple has these free online lessons? Might find something of interest to you. Not an exhaustive list, but it's all free.
If you want to go more into depth, I can personally vouch for Lynda.com training. All you need is a good connection and QuickTime (and $25/month). You can cancel at any time, so it's also good for if you just want an intensive course in a particular software for a project you're working on.
