When you're in a wheelchair it's a lot easier to negotiate a computer than a book. Anyway, the newer Macs are very low on power as they're using 5nm chips, and before long will be down to 3nm which consume ridiculously little power.
Getting electronic copies of annual catalogues is a great idea and also good for the planet. Hardcopies take up space on the bookshelves. I would still want hard copies of books like ESC as they only get updated once every two decades.
