At the end of the day it comes down to being able to use the software. If a product works, whether it's open source or not, you'll use it. When both open source and proprietary products are equally buggy and for the same reasons, we shouldn't be so quick to dismiss either one. Instead, we should carefully investigate what's available and choose what actually works. For most consumer needs, open source will still get the job done, bugs and all. For more specialized needs, proprietary may be the only game in town.
Sometimes fanboys need to be reminded that there's still no silver bullet.
