The memory in the PC I put together early last year is now worth about three times the total cost of all the parts I used to build the thing. It is absolutely crazy.
I really like the reMarkable tablets, but they are still not quite the replacement for a paper notebook that I would like. I think the main problem is that the refresh-rate/software is slow enough that trying to "page through your notebook" to find specific notes is a grueling experience. The alternative is to just make lots of one page notes, but things still become difficult to find (not to mention you add a lot of stress coming up with good names for stuff...)
I was kinda shocked by the results of his informal survey, because this was a big focus of my ethics course in college. I guess a lot of developers either didn't get a CS degree, or their degree program didn't involve an ethics course.
