This is maybe a bit of a tangent to this article,but I've tried so many pieces of tech over the years to replace pen & paper notebooks, mainly iPads and eInk based notetaking devices, like the Remarkable.

While I cannot find a concrete flaw with these things, with some of them working quite well, I just couldn't really get a feel for them - they always felt so tech-y and imprecise, that I always went back to an actual sheet of paper.

Another product design misconception I think a lot of companies make is the use of metal cases - metal feels high-end and durable as opposed to plastic I suppose, and with it being quite solid, manufacturers can make it thinner and lighter.

But it's uncomfortable to hold, and hard to manufacture complex shapes, which means these devices often end up in a case. Man I miss the 2000s when product design wasn't dead.
