Another 2 pre-purchase questionw here.... 1. My idea is to hook it to an external monitor, and use a bluetooth mouse and keyboard to work. If I go with either an iBook or a PB, can I run it with the lid shut? That's be much nicer than keeping it open... 2. I have an old 14" VGA Samsung monitor - can I hook that stright up to a PB or iBook? Do I need an adaptor of any sort?
