The pocketability of the NIT's is a real advantage for this usage case. My kids are 2 and 4 years old, so things can go from calm to explosive in a second - the ability to quickly put the NIT away in my pocket, on a small shelf, etc and quickly tend to them is a big plus IMO. I have used it in all the scenarios described so far in this thread, and it is well-suited for all of them. The kids factor actually was the reason why I started to look into the NIT's in the first place. My computers are in the basement, but the kids play on the main level, so I wanted something that gives me the full internet in the palm of my hand. For the big stuff, I go downstairs after they are asleep to use the desktops.

Think about all the stuff you lug around when you travel with your kids - portability/capability of the NIT's is unmatched, especially if you want to minimize the amount of stuff you take along on trips with the kids! Just my two cents!
