There seems to be an evolution in the IT space where system integration is migrating to browser integration. Therefore the browser is the new application platform. When this happens the platform operating system will have less import because the application will not be native but in the cloud.
Enter Linux. Think of this is as the second coming mainframe technology. Applications being available through web portals though instead of emulators. Eventually users will be able to access their application no matter what code it was written in and the OS will need to be the following: CHEAP, fast, secure, standards based, and open source (if possible).
I can think of quite a few that fit the above description.
