We're investing in two Macbooks for our startup iPhone iTouch app development business, and we're much more concerned about protecting our investment than the aesthetic aspect, so I'd like to go overkill in terms of protection. I like the Invisible Shield concept - is there a neoprene or plastic or rubber casing that can make the macbook even more clumsy idiot-proof? What is the best in terms of protection that people have experienced? Thanks guys! -Evan PS) On a side note, is it reasonable to expect new Macbooks in the next two weeks? If not, I'll probably pull the trigger in a week. Also, what's apple's policy on returns of products purchase just prior to an update?
