I was sat with my AlBook at a rather lengthy meeting on Friday to which a couple of other attendees had brought their PC laptops. Though considerably less attractive, their plastic cases are certainly more rugged than our lovely, but delicate aluminium/ titanium. I still think fondly of the final release of the G3 Pismo Powerbook in this regard. All the best, Colin.
