I was just thinking the other day, my folks are using my old 2011 MacBook Pro 17”, it helps my dad with failing vision immensely. I looked for some things for him online, and my god it’s an amazing machine. I maxed out the RAM and put in an SSD a few years ago for them. The things runs modern webpages just fine, the keyboard is a pleasure to type on: it has almost full-sized keys! Up the resolution on the display and give it modern internals, it would be the perfect laptop. Doesn’t need to be 1mm thin, and the weight is a fine compromise for the computing power you would get.
