haha.. very funny.. some of travel and use our powerbooks in nightclub environments, where it's quite uncertain as to who will be hanging through the dj booth window..
also.. today on the NYC subway, the train ceiling Air Conditioner leaked on my powerbook !! (that's what reminded me I could use something like this!)
I know this helps in no way, but I'm shocked that you actually USED your PowerBook in the NYC subway and have lived to tell about it. Times must have gotten better...especially in the subway....since I used to live in NY 15 years ago...
If it's really packed or I see shady peeps around.. It stays in my bag.. but around 11am, it's usually a pretty OK time to pull it out.. I figure thiefs are more interested in the million ipods and PSPs that are all around..
plus, I want to advertise for my favorite computer !
actually, it turns out that iSkin claims to be water resistant, so I'll probably just go that way.
