ReactOS has delt itself a massive blow by hiding so much of their progress.

The project has insisted on creating Windows Server 2003. Probably very little of the software you want to run works on Windows Server 2003. Certainly no modern web browser will.

There has been some movement in recent months though. They have a 64 bit version. They are implementing NT6 APIs. They are implementing UEFI. They are looking at WDDM drivers. The have synced with Wine 10.

If ReactOS can produce a version that can run a modern browser and maybe a half-way recent Office suite, I think a lot of people would change their mind about the potential.

If they can support modern GPU drivers, it is possible they could even gain some traction in that space. Lots of work to do but not impossible.
