I'm enjoying this book - seems to be leading in exactly the direction my thoughts have been going regarding philosophy and research - surely a mighty co-incidence. I observe that Nardi uses a lot of stuff from HCI without knowing this stuff you miss out on some of the richness - (e.g. p28 mentions Fitts law - I looked this up on wikipedia and it's simple enough but you do need to be able to quickly check these terms out. I dont see much in here unless you're into HCI - i.e. not sure how much BJET readers will be fussed on this book.
