The suggestion to print [a lot] doesn't seem well-justified. Compared to reading on a portable device, consider all the paper usage (waste?) and ink cartridge expense. For folks like me with tight budgets, there's no way I would feel comfortable printing out the same volume of articles that I currently read on the computer. With ink cartridges priced like they are, I am very frugal when deciding what is or is not worth printing.
