I keep all of my books as PDFs on Mendeley. If a PDF is not available, I buy a hard copy through Amazon and send it to 1DollarScan to be converted to a scanned PDF.
I can’t easily consult half a dozen [e]books at once.
In terms of screen estate, I agree, but in terms of looking for something in textbooks, I find it much easier to consult multiple ebooks at once, since I can easily search through tens of them in a second.
