Over the years I've managed to bang my laptops around pretty hard. Somehow they survived. Not too long ago I dropped a Dell laptop straight on the floor from a height of about 3 feet. I thought for sure it was going to be useless after that. I was wrong. It kept right on running - no problems! I was definitely amazed. Good thing the floor had carpet and padding!
Anyway I discovered that there are some very rugged laptops built specifically to withstand shock, moisture, drastic temperatures, and more.
Head over to Glacier computers and check out their line of "rugged laptops." From the looks of them they look like you could bash them around plenty and they'd still work just fine!
