I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
I just write on it with my Samsung pen. No conversion in normal text needed. That makes your tablet just like a big piece of paper where you can add unlimited more and can find everything you want very easily. Personally I use oneNote for my notes, because it syncs with my PC and everything is saved in the cloud. But the normal Samsung notes app is pretty good too.
