My grandma is hard of hearing so she prefers written correspondence.
Getting older myself (worse eyesight and a much worse hearing) I would not have thought about that but that's a good point you're making.
Like typing on a nice keyboard.
I also appreciate a nice keyboard but I also have a hard time finding anything that suits my needs. My granddad taught me to touch-type when I was still a little child (even then, I wanted to write stories and make 'magazines' for my friends) and si I learned on his old full-mechanical and full-metal typewriter (an Olympia SG1, if anyone is interested). Compared to this wonder, all keyboards do feel a bit plasticy and lightweight to me ;)
Also I can change the color of the inks to match the season, stamps, and whatever.
Younger I liked doing that too. Nowadays, I use two, three inks at most.
The same here. I've tested many digital journaling app/services but I always come back to the good old pen and paper. And not just because I care my privacy (I do). It just feels nicer.
I also draft my blog longhand, btw. Nice to meet someone else doing the same (could not find any URL to your blog in your profile, don't hesitate to share it) :)
