With their new stock sale, Google has plenty of money for internal development and for purchasing tiny technology companies (mostly to get the people).
Like many people, I have an idea for how Google should spend their money :-)
I think that it would be very interesting (but a huge risk) to try writing a Windows/Linux replacement desktop that would act the same on both systems.
For Windows, they would provide a new shell (other people have done this) that would integrate file browsing, search, program launch, command shell (of course!!), FireFox based browsing, etc.
For Linux, the implementation would be a new Window Manager.
In addition to an expensive development effort, there are a few other large problems to be solved:
- Microsoft would try to torpedo the Windows shell replacement - it would be very bad for their business model.
- It would be difficult to support the multitude of Linux distributions
