Thanks for all your opinions gents - much appreciated!
I always enjoyed David Pleasance's interviews and guest columns in the mags back in the day too (and the contributions from Dave Haynie and RJ Mical are a great bonus!), so I think I'll be going ahead with my order for this book now.
Pity, though, that people who ordered early from AmigaKit got their copy before some Kickstarter backers did!
Same thing happened with Kickstarter backers of Bruce Bagnall's Amiga book, didn't it?!
