Check out what the Intel App Store on Moblin looks like, where it does not resemble a direct port of the Windows version (whether it is a good or bad thing, we leave that up to the user as different strokes work for different folks). The interface has been specially customized in order to provide a consistent feel with the Moblin interface, while you will be able to notice a more focused attention on open source applications. One thing similar with its Windows counterpart would be the ability for your purchased apps to run on up to 5 different netbooks. Nice to know that you can also launch apps straight from the store itself.
