Off-topic, kind of (but maybe not)
I've never really understood this sentiment. I too spend my working life in front of a computer screen. This time, however, is not spent reading gaming material. It is spent coding and running simulations and writing papers and reading papers. When I get home, I plunk down in front of my own computer, and do things that I like, such as reading gaming material and playing games.
Other than the medium itself, I don't see a similarity between working on a computer and leisure time on a computer. Heck, other than a remote instead of a keyboard, watching TV could be considered just more "screen time". The difference is the content.
I'm 35 and I've used computers most of my life. In high school, throughout university, and for the first few years of full-time work, I spent a great deal of my leisure time on the computer. I am now firmly in the "I spend all day sitting a computer at work, and I don't want to do it when I get home" camp. I don't like reading long articles (much less novels) on a computer screen, and my electronic gaming habits have almost completely shifted to game consoles from PCs.
Watching TV and looking at a computer screen are both still staring at a screen, but there is a difference between sitting two feet away from a 20" screen and sitting ten feet away from a 52" screen. After spending 8 or more hours in a day staring at my computer screen, I don't suffer the eye strain watching TV from the couch that I would if I sat at the computer at home for the same amount of time.
Likewise, sitting upright in a desk chair using the keyboard and mouse has me in the same position I sit in all day, performing the same repetitive movements. The postural strain makes it hard to feel relaxed. Lounging on the sofa in front of the big 52" TV gives my body a break from how I sit at work. Using a gamepad or Wii controller to play a game instead of the keyboard & mouse gives my arms a rest from those repetitive motions that I perform all day. Plus, if I'm on the computer, I'm pretty much entirely on my own. Watching TV with my wife is better than watching the same movie sitting at my desk by myself. Playing a game on the big TV while my wife sits with me, even doing her own thing, still gives us some time together. We'll still chat from time to time and she'll watch parts of the game I'm playing if it's of interest, which would not happen if I was hunched over the computer.
That's why it's certainly a valid sentiment for me. My arms, neck, and back need a break from sitting at a desk, my eyes need a break from staring at text on a computer monitor, and my wife and I get to spend more time together.
On the actual topic of this thread: I will probably get more gaming use out of Dragon and Dungeon in this new format, but I miss having the paper copies to read in bed, in the bathroom, or just relaxing on the couch. I don't really buy any gaming PDFs if there are physical versions available for the same reason.
