I carry my G3 900 iBook EVERYWHERE, and transport it in our motor home, use it in a recliner on my chest nightly and have never had a problem yet. I did purchase a "handle" for it, though; best $40 I ever spent! Valerie More information on the "handle" please ! I loved the handle on my first two clam shells. I heard that Dr. Bott made one but haven't been able to find anything lately. Linda SE Michigan
