For some things (e.g. a one-off need to address an envelope) they are still faster and easier than anything else.

...except a pen

I don't think I would write faster with a pen than with a typewriter..?

Yes. But for the one off need described (or similar) it’s way faster to write an address than to get things set up with a typewriter.

Of course for certain forms, better legibility in many cases may make it worth it.

Yes. Post Office OCR is pretty good, but deliverabilty of hand-addressed envelopes is not as good as with typewritten addresses.

If you have really neat block printing it might be a wash.
