[Error: unknown template qotd]Now that I have one, my Nintendo DSi, especially if I'm going to be stuck in a car/plane for a significant amount of time. Or if I'm stuck in a hotel room because I can't go out and do anything. Further more, I always make sure that I have my digital camera, as I'm something of an amateur landscape photographer. (Various works can be found
here.) If I can swing it, I also bring my computer so that I can download photos after I've taken them. I may not be getting online, but it's handy to have to I don't constantly worry about my memory card filling up. If I'm bringing my iPod, I also find it handy to bring my computer so I can charge it if I'm staying in a hotel and spending the day sight seeing. That way I have music while I'm hiking or for in the car.
Since my cell phone is the only way someone can call me, I always have it on me - however I try not to use it much save the occasional phone call or text message, or the really random Facebook update. If someone is calling just to shoot the breeze or is constantly pestering me with texts, I will tell them to knock if off and/or start ignoring them.
