Capitalism has spurred the competition that makes CPUs faster and 
faster each year, but the focus on money makes software manufacturers 
do some peculiar things like deliberately leaving bugs and deficiencies
in the software so they can soak the customers for upgrades later.
Whether software is easy to use, or never loses data, when the company
has a near monopoly, is almost irrelevant to profits, and therefore 
ignored. The manufacturer focuses on cheap gimicks like dancing paper 
clips to dazzle naive first-time buyers. The needs of existing 
experienced users are almost irrelevant. I see software rental as the 
best remedy.
