@Efficiency:No, spaces are still the default. If you care, you can of course, change it to tabs. If you REALLY care, you could always write a module to remove ALL whitespace from your markup as well on the way out.
"Desktop (non-Metro-style) apps will be able to be promoted in the Windows Store if they meet Microsoft's Desktop App certification requirements, and will be discoverable via the Windows 8 store. Windows 8 Desktop Apps will be neither licenesable nor downloadable (i.e., able to take advantage of the Windows 8 "fulfillment service") from the Store. Instead, Microsoft will only provide a link to the Windows Store for Desktop Apps on Windows 8 on x86/x64 and ARM."
@Shawna Mann: It depends the country. In the US, people can buy apps with their phone carrier account instead of a credit card. Agreed it will be nice to have other options though. Hopefully they'll open it up a bit after this app store succeeds.
