Who would want to use a datasette in 2013? It was revolting in the 80s - only those who could not afford a disk drive used them. The Commodore 64/128 were only enjoyable once a disk drive or two were attached.
It is like using a Amiga with no hard drive. Completely annoying with multiple disk swaps giving you RSI. If I am going to do repetitive things with my hands I want the experience to be enjoyable ... not annoying!
