All in all, a good book - but I'm looking forward to "the art".
Staying by Dave Thomas, I've done his sixth kata "anagrams" a few times and I always learned a new shortcut, trick or whatever. I rarely use the mouse anymore and I've downloaded ReSharper (because we're using NUnit instead of MSTest now) and took benefit from the smooth integration of the refactorings. DevXpress had to go unfortunately.
Here, I've found a nice introductory-video in the principles of coding katas, if you're interested.
Here is a video about the randori-variation.
Uncle Bob takes this approach a step further and declares coding kata as an art. See him performing the prime factor kata to music! here.
