I am a SSgt in the United States Marine Corps and I just recently returned from a 1 year tour in Iraq. I bought my clamshell off ebay and had it shipped to me in Iraq. I then upgraded the ram to 576 and installed OS X tiger on it... I was a military advisor to the Iraqi Army and used the clamshell every day to work on admin issues with them. Last March my hummer hit an IED (Roadside Bomb). The clamshell was inside the hummer in its matching mac case. I was the gunner and sustained minor injuries. The clamshell however survived with only a minor hairline crack above the ethernet port. All the marines could not believe how durable my 6 year old clamshell was. Since then I upgraded to a 120 GB hard drive and it still runs awesome. The clamshell iBooks are DEFINELTY combat proven!!!!!!!!!
