Aaronson is fabulous. In my opinion, possibly the best technical author around these days. If you haven't already, his new book[1] is absolutely worth checking out, especially if you're unfamiliar with quantum.
His book is seriously awesome. It's in a weird space technically -- not sure I'd recommend it to someone who didn't take a least a few math or cs courses as an undergrad. But if you have, wow, it really shines some new light on things you thought you probably understood well.
