I would also love the MacTech CD, but seeing as the material is online I have never bothered looking into ordering it. The old MacTech and Develop articles are great stuff, and often the only place to find the info I'm after these days. It certainly seems bizarre that the CD (and so presumably the new THINK Reference) requires OS X 10.4!

If I recall correctly, THINK Reference integration with THINK C only happened quite late in the piece - with THINK C 6 or 7, and by then THINK C was going rapidly downhill as a product.
