I carry my MBP around from meeting to meeting. Very scared of dropping it eventually. Are there stickers out there that won't hurt the finish but provide a good grip?
You could always put it in a backpack or something, too. I'm not how sure how unprofessional that is at your meetings and what not, but it's valid for not dropping it as far as I'm concerned. Perhaps some sort of carrying bag that won't sacrifice your manhood?
