ReactOS is an amazing achievement, for what it is. Building a house is much easier than building exactly the same house without being able to even peek at the original blueprints, or take input from anyone who has.

To that point I hope that more people study ReactOS and get a sense for the Microsoft/IBM philosophy of doing a desktop operating system (which is completely different from the Linux/Unix way). I hope we someday see new operating system projects that use these learnings.
