Why Excel still dominates the market

Sure, there are many reasons. My point for posting is that one of those reasons is that people with any skill set can, and do, pick it up and bend it to whatever purpose they desire.

There have been a number of HN discussions over the past few months debating why "inferior" products like Excel can continue to dominate while solutions that are "better" are constantly struggling to find market share. Having a program that is somehow useful for everyone from major banks to 80 year old retirees is an important factor in the longevity of this software - even if it isn't necessarily the perfect tool for every use case.
