Lotsa good thoughts here, especially about the fact that you have written books already of which you can and should be proud.

Kevin and I have a couple of old clamshell iBooks that we've loaned to fans who've been without computers for a bit. They're running OSX (Tiger). Slower than modern Macs, but decent for web surfing, email, etc. If you'd like to borrow one, just let us know. I'm not certain if they have iPhoto on them already, but it shouldn't be hard to put it on one of them.
