In order to get the JustEnoughTechnology seal of approval devices don't have to be built from Bakelite and powered by a bucket of sparks. Watching a classical music concert I was intrigued to see that instead of a paper music score each musician had a thin LCD panel showing the current page. This is a triumph of the effective use of technology. How do orchestras cope with paper scores? They need lots of copies for every item in their repertoire. The benefits of ease of storage and retrieval must easily offset the cost of the hardware. In addition the ease of "printing" new works and marking up scores with conductors annotations makes these even more useful.
