The rules bloat is certainly a concern. As far as PDFs go, those cost me extra, because I buy my books at the FLGS to support it. Which brings me back around to another point you touched on. I've noticed on message boards people are quick to assume that gamers have access to computers, but I know several people at the FLGS that really don't use computers for their RPG gaming at all.
By the way, sorry for transposing the characters in my short-form of your name. Think-o.
I do the same as you; I buy my rules books at my FLGS and then buy the PDFs online, for the exact same reason. Part of my point was that you don't necessarily need every book though. If Carrion Crown (to continue your example) references a handful of monsters in Bestiary 2, you can easily pick up the PDF without ever buying the book. Yes, that's an extra $10 to run CC, but you only need to ever buy the book if a} you want to, b} you decide you like the content.
As for assuming gamers have computer access, frankly I assume people in general have computer access. It doesn't much matter if you've got access at the gaming table. The GM can print the four pages from Bestiary 2 he needs, before the session. The player who's drawn on three different PDFs for Feats/magic items/racial abilities/whatever should have copied & pasted the text onto his character sheet. I don't use electronic goodies at the table... I've already extracted what I need, no matter what side of the table I'm sitting on.
Anyway, your concerns aren't invalid. They're yours. But I personally don't feel troubled by them. I buy what I want to buy when I want to, and don't worry too much about the rest. Just like every other product line.
