I liked it. My least favorite part wasn't the book itself but rather DrRacket. DrRacket's not bad, in fact it has some slick features, but I don't consider it great either. As an IDE it's good, but as a text editor it's poor. But then again my brain has been poisoned by Vim, DrRacket is probably great for young students without preexisting biases like mine.
I've been using racket for almost all of my recreational programming for the past few years but I don't do it with DrRacket.
My first, first year CS course [1] was based on HTDP and used DrRacket extensively. I, on the other hand, did all my assignments in Emacs. Worked completely fine for me.
