I can' t easily use half the microwave or stove interfaces I run into. Computing, by any sane person's standards, is not something that is easy to do. Despite the incredible amount of time and money invested yearly, computers have yet to cause productivity increases in most areas. In many cases they actually reduce productivity. 1 Programmers are not trained to care about, meet in person, or think like the users who use their software.
Many software companies charge for customer support.
To my knowledge, my TV or microwave have never crashed. This is not to say that either my microwave or TV are usable, it's just that they tend to be reliable. Just as architects must consider the social and aesthetic implications of their creations, so must computer software and hardware developers.
