Well, that's the balance between features, bugs, and cost. If consumer software companies were working more like, say, people working on Curiosity (Mars' robot) or aircraft navigation software, you could have a phone that does much less but without bugs. The reason why it is this way is because people usually prefer to cope with minor bugs that giving up on features. Plus, when you buy a product, you usually know the list of features but not the list of potential bugs. So you can make a company that sells phones with 0 bugs, with a 2004 set of features. Or an OS that focuses purely on providing a bug-free experience, but 5 years late. Not sure all that would sell well.
