I think this is a fantastic idea. We all tout the benefits of digital...easier, unlimited storage, able to index and search, etc.

I've sent my wife thousands of texts and emails over the years that are long gone.

Every single letter and note I'd ever written, no matter how stupid, she's saved in a box and looks through almost every year. There's certainly something to be said for the human element and effort of it. Just in case, hey, why not both?
