The aforementioned just about covers it for sure. I may add that I take my iPhone for it has just about everything from gps, hotel reservation #'s, gas station info, email, banking and so on an so forth. I also make sure your insurance is up to snuff for that warm and fuzzy feeling .... I'm insured by Smith and Wesson if you get my drift :s
