"As far as app stores go, though, Microsoft still has another ace up its sleeve. Windows 8 will span desktops, laptops, netbooks, and tablets -- and if Microsoft gets it right, you'll have just one app store for every Windows form factor. You'll be able to install a word processor on your desktop, and it will automatically deploy itself to your tablet -- and your documents will be automatically synchronized, too. There's no reason it won't work across the x86/ARM divide, either -- Windows 8 ARM could use the same app store as its x86 cousins, and it's entirely possible that the same store could contain Windows Phone 7 (WP7) apps that will run on Windows 8 tablets. Let's not forget that Microsoft already has extensive experience with digital distribution through Xbox Live, too -- and yes, the Xbox Live Marketplace could also be integrated into the Windows App Store." - LANjackal
