Kindles in stock + economic stimulus

Amazon's Kindles are in stock again. If only a chunk of money were to appear in my checking account this week for no good reason...oh wait, it did.
I'm wondering how well the selection of technical reference books are for the Kindle.
No Applied Cryptography, n Mastering Regular Expressions, nothing on Groovy, the only thing I could find is the classic Pragmatic Programmer.
I'm planning on getting into consulting. I think it would be very helpful to have a collection of my favorite books in one small appliance. Computer books are heavy.
If I did more casual reading, I would be jumping on a Kindle, but I'm going to wait.
