Lots of interesting commentary on this topic. I'm, um, way over 35. (Okay, I'm 50.) I'd definitely be considered an early tech adopter. Got my first ereader over a decade ago. Paid over $300 for an original Rocket eBook and had three different iterations of that over the years until getting my Nook (3g/Wifi) for my 50th birthday last summer. While there is a ton of free content available via completely legit sources, there's also plenty of ways to find the morally ambiguous stuff too. I found the Harry Potter stuff in PDF through an on-line "study" group. Perfectly rendered. I've spent cold hard cash for the hard cover versions, so I don't feel like I've hurt Jo Rowling's pocketbook any.
BTW, in a tangential discussion, my niece (age 20) called me yesterday looking for tech advice. She owns a Nook and is headed abroad for a semester of study. Wants a Kindle for easier access to materials. "Aunty, how can I move my Nook books to my new Kindle without having to pay for them all over again?" Trust me, I told her exactly how to do it. (And gave her the link to MobileRead!)
