2) At the moment, we're not sure whether we'll continue to be able to give out free electronic copies with physical copy subscriptions—it's possible that people may have to buy one or the other. On the plus side, we *will* be offering a big 30% discount to make sure that the books remain roughly the same price folks are used to.
If the included digital copy goes away, I would be very sad. I don't think I'd be sad enough to stop my subscription, but I would be sad. I tend to read the digital and physical copy concurrently. During lunch, I'll read the book on my iPad. At night before bed, I pull out the physical copy and read it by red filtered flashlight (so as not to bother my sleeping wife).
I'll continue to follow this, and I know Paizo will do a great job keeping us informed of what decisions they make and why. It's one of the things you do well as a company! :)
