Apple - iPad - See the web, email, and photos like never before. is a good place to start. I'd also suggest looking at an Apple store, looks like quite a few malls in IAH have 'em. If you're there, you can get a live demo and see what they're like. There's a "3G" model that doesn't need wifi (uses the same system as what internet-ready cell phones use) but I don't think it'd work in other countries, and there are monthly fees involved for using those networks. Wifi is another option on ALL iPads, but then you might have to pay airport wifi fees. No extra charge for free wireless access points, like at home or airports like LAS or SLC.
