I disagree with the premise of the article. On average, Free software seems to have better usability proprietary applications.<p>Furthermore, usability is rapidly improving, since developers seem to be becoming more aware of usability issues in general. Sure, there are examples of horribly unusable apps, but I find the ones that suck the most are the proprietary windows apps, even the ones from big companies, and some of the most usable and consistent apps are open source.<p>Even so, there is always room for improvement, and the biggest issue is simply the lack of developer time to implement all the great usability ideas that pop up.
