My recent comment[1] on the remarkable thread[2] got me thinking about the ideas which in my opinion did not reach their peak before they were obsoleted, not due to technical merits but due to business factors.<p>I see a lot of people who assume that all of the latest technology is a superset of all the advances that came before it and that everything we have today is better than whatever was created before. What kind of examples prove this assumption incorrect.<p>In terms of devices, I think these are things that were very innovative, useful and sadly do not have an suitable replacement today:<p><pre><code> a. The palm pilot or any of the PDAs for that matter
b. The nokia 900
c. The nokia 810
d. The pebble
