A few years ago and the CAST conference, I talked to one of the owners of Dorset House publishing and they told me that they wouldn't be offering their books in Kindle editions. Today, I just noticed that at least some Dorset House books are available on Kindle. Peopleware was the one that caught my eye.
Although I have a paper copy, I ordered the Kindle version so I have it available wherever I go.
Thanks Dorset House!
