I just found this and bought myself a copy:
It appears you can get it for as little as $4.98 ($5 of your purchase price gets rebated as credit). I have absolutely no experience with digital-format books, so I’ll be experimenting. But if you want to read Couch and you’re a digital-reader type person. Well, bingo!
I’m going to see if I can’t get it to my ipod touch and read it via eReader. I hope it’s as good as they say!
In the meantime – I’ve been told that the actual book will be shipping from the printer sometime this week. Nifty.
