On the point about "dead trees", you will find a lot of printers/paper producers these days plant more trees than they use. In some ironic twist, books are better for the environment as the energy of digital books is "gone". A book doesn't use more resources to read it. Also the device you need to read a digital book uses resources, the servers used to store the digital books use resources, and so on.
I still prefer digital books as I can carry 100s of them around on a single device... and I can power my devices with a solar panel (which I do when travelling!)
So yes. I send a digital book, or something I can log into.
