Hi Till,
Thought you should know that something faintly wonderful and mildly disturbing is emerging here. To wit, you are becoming my guru! Although in my case, that should read "to half-wit".
I went off to Amazon and had a look at Krugg's book - never heard of him before. Liked it immediately when I went through the sample pages there - and was completely convinced when I read Dan Gookin's review. Dan is my favorite computer author so far.
"
Jacob is not always right" Very true - but he's not wrong either

We're talking usability here after all, and as in most things context is everything. Reminds me of the old question "Are Rolls Royce cars better quality than Ford?"
The value of people like Jakob or ***-hard hand-coders or staunch vegetarians is that they keep you aware of the trade-offs you are making, which is always useful even if not 'right'.
Anyway, thanks for the tip - I ordered Krugg's book for under $13.50 total
Mike.
