Teach Yourself Logic, new layout

The Teach Yourself Logic Guide has a new look.

Now, instead of being a standard A4 PDF, it should be an ideal size for reading on screen. Read it either (i) on an iPad (download in Safari, open e.g. in iBooks), or (ii) on a lap-top (e.g. read two pages side-by-side using Adobe Reader in full-screen mode). The changes in this new version are modest, then, but should I hope make the Guide significantly more readable.

Comments on the new layout, for or against, are welcome.
