>> Until this changes we won't see much progress of open-source in the real world. What's the "real world" here? Open Source software has made great strides in the mobile and server/datacentre space. Open source UIs used by the general public, less so sure. But then one could argue that most of the UI frameworks people use these days are open source and written in JS...
Real world, as in non-technical users. Yes, open-source libraries are indeed everywhere - I was talking about a complete open-source OS, like a Linux distro. Sorry for the confusion.
Linux distros are huge in the datacentre and server farm, and AFAICT Android is open source....
But I do know what you're getting at, and Openmoko had a huge problem with UI/UX - it's not even that it was a bad UX, it's that the underlying platform was constantly shifting so radically that there wasn't a good base to build UX on!
