What throws me for a loop is that Todd Rundgren, known for his prolific career in music, was the developer of a companion program to this tablet (and more).
this is actually why I submitted it! (I put the Todd Rundgren fact in the headline but HN mods apparently thought that wasn't relevant). He's mentioned it briefly in a couple interviews (like that Guardian article you linked, and on a podcast with Bob Lefsetz), but I have yet to see an in-depth article about Todd's career/hobby as a software developer. I'd love to read an article only about that one day.
