Saw this product this morning, the PlugBug, which is a pretty clever attachment for Apple product owners. It connects to the Mac Book Pro / Air power adapter just as the normal 110, 110 extension or international adapters do, but adds a 10W USB jack for powering a 'pad or 'phone as well. Very clever.
Here's the link:

It's very AJAX, used my previous information very well, the shipping choices were incredibly clean and well laid out ... in short, the whole mechanism was one of the best checkout layouts I've seen yet. And as a connoisseur of checkout mechanism (and the author of too many to count) that is saying something.
I'm not sure if it would have been quite as cool for a brand new customer (I was a returning one) but it's still very well done. Worth a few moments research if you're into such things.
