Hello everyone! Last October I switched with the purchase of a G5 imac, and now I've just added to the family with a 12" G4 ibook. But I was wondering, what can I do with it? Obviously I will take it to lectures, seminars and the libary, but what features should I know about? 1) Syncronising. Is it possible to sync it with my imac? 2) Airport. Can I share the internet from my airport extreme on my imac, and then use it wirelessly on the ibook? 3) Cleaning. Any tips for cleaning the screen and inside the laptop? 4) When the ibook is closed, there is a gap of just a couple of mm between the screen and the keyboard. this is normal right? 5) Other tips. Anyone got any? Thanks all! & I look forward to the responses.
