Other than the watch, all the products you mentioned are before 2002. Anything in the past 20 years that have been huge misses in delivering up to expectation?

Also how is the 1st gen watch a failure? It sold millions immediately, and was a huge commercial success. It pretty much started a gold rush for digital watches again.

I think it's fair to say the new "Apple" (last 15 years or so), has been pretty good with exceeding expectations and breaking through barriers that other companies just couldn't.
