So proprietary software is, and will remain, a vastly superior model until the day that open source can claim to have created as much wealth and productivity as proprietary products.
The Windows ecosystem is a huge market that has created more wealth than ... well anything I can think of. In fact, open source really owes its existence to Windows, as much as people don`t want to admit. Windows is the reason cheap computers exist. Windows is the reason that people can buy a great compiler for a few hundred bucks. Windows is the reason that most of us can afford a computer.
