@fuxoft Oh, missed the part with "writing via Morse".
I expect, majority of the people (buying this) will use just notifications via Morse.
The writing is even higher "geek factor" and there are still people using Morse code today. They are - probably - the target audience of this product.
@Rado1 Just measure how long it will take to write the simplest message like "@fuxoft I will be late today" using morse... And what will you do if you make an error during the typing?
