I can kinda see where they are going with this. Although I would probably never use it (I very rarely send a letter by regular mail), I can think of some use cases where I could use it. My great grandma doesn't use email. I don't think she even has a computer. Every time her or my great grandpa would send me something it would come with at least a page of a letter just telling me about how they were doing. I also never seem to have any stamps. So in lieu of going out getting stamps and writing something on paper, and buying getting envelopes, I could just send an email. I mean if it is rare occasion why not? It's going to cost me like $20 for the stamps, maybe $10 for the envelopes. Thats just to send one letter. Now if I sent letters all the time the investment of stamps and letters would be worth it, but because the next time I am going to send one again will be months, years, whatever, I will probably lose the envelopes, the postage will be raised and I will need more stamps, and my grandma will never get a letter.
