Same here. I've found the new iPad Pro + paper like screen protector to be a very near real experience with very little noticeable input lag for notes. Now, it is a very pricey alternative but agreed on all points.

I did consider the Boyue Likebook Muses [0], but figured for longevity the iPad may be the better buy. I did try the reMarkable and was very disappointed in it's price to performance/usability, at least for me. Little things like no backlight at that price point was hard to get over.
