It might have the look and feel of XP, but I doubt if it will run every Windows program. I’m thinking Windows will eventually install on Linux the way it does with Macs.
The core OS will be Linux/Unix, and Windows will run as a GUI interface. This may seem stupid, but there are a lot of applications, including mos games, that only run on Windows.
I am hoping that in five years or so you will be able to hot switch between OSX, Windows and Linux interfaces, and run all their programs. If the OS is secure, Windows exploits would be disabled.
I like the idea - basically like switching between gnome and kde. I’ve used WINE/Crossover for many win-apps on linux, but there are some limitations with functionality and performance.
Leaving only the Linux and OSX exploits?
How about virtualized Windows, OSX, OS/2, VMS, MVS, AS400, HPUX, System V, Solaris and Linux. All running under NetBSD.
