@neverwhere,
Seriously, are you all so extremely short on money?
E.g. "Atomic Suicide" costs $20 new, and is already available for $12 used.
That's almost nothing.
I personally absolutely prefer reading in a book, than on a display.No comparison to me.
For IMHO especially Dr's books are not these which you just read and put away, but which you over and over study and reflect upon...
But as said, this is just my opinion and advice.
Wish you all the best, peace and light.
