Could still work on Windows (which is the bigger market anyway) whitelabel it and sell a version to Dell,Sony... you get instant traction and the vendors are happy (percentage of proceeds) but of course you have to sell it to Dell, HP, and Sony...
I had thought of that. As soon as the idea went from building an app store that I would use personally to one that would be Windows-only, I knew that I wouldn't be passionate enough about it to succeed.
