I've never figured out why the inordinate delay given that millions are unhappy with Windows and Microsoft generally. You'd reckon open source developers would be falling over themselves to join such a project but it seems not.
Perhaps there's something about how the ReactOS project is run that I'm unaware of that puts people off. The other problem is trying to find out news of the project, the ReactOS website goes dead for many months at a time and updates are at times years apart. You'd reckon its developers would be much more communicative, and I reckon this is one of the reasons why there isn't more interest in the project.
The fact that ReactOS is going nowhere is most annoying, having no alternative O/S to Windows is a real pain.
BTW, I've tried every every release for years and I have been unable to get a stable enough release to run even one dedicated task. (Some of my tasks such as email or wordprocessing could be put on a dedicated machine so it was the only user-installed software, that way an unstable O/S wouldn't be stressed too much but unfortunately with ReactOS even that idea hasn't worked out.)
