Heard about this book through the IxDA mailing list: Thoughts on Interaction Design

Apparently was published in a limited run in 2007 and is now out of print with no plans to republish in a printed format. It’s available online, however, and the contributors come from a variety of heavy-hitters: Apple, Google, frog, CMU, and others.

I’m curious whether anyone has read it? What were your thoughts?
