I thought it was the case, and now there's a study -- reported in Fast Company at The Pen Is Mightier Than The Phone: A Case For Writing Things Out -- that bears me out.
Writing, on paper, using a your own hand, is often better for creativity and for thinking than typing! It's also better for remembering:
By committing your thought to paper, you're also doing more to lock it into place. ... as your hand executes each stroke of each letter, it activates a much larger portion of the brain's thinking, language, and "working memory" regions than typing, which whisks your attention along at a more letters-and-words pace.
For me, every important project I work on has a significant part of its life as ink scrawled onto paper.
Don't let those handwriting muscles atrophy!
