With so many apps running around the Windows playground, Microsoft wants the grown-ups to be in charge of Metro. Programs for the new interface will be available only through the Windows Store, which will allow one-click installs, user feedback and crash monitoring. Developers shouldn't worry too much, as the heavy lifting for those features will all be handled by the OS. Redmond's demanding some tit-for-tat, however, asking programmers to resist the temptation to invoke APIs not included in the development kit. All the software will be vetted, App-Store style, while access to devices like GPS and cameras must be granted by users before the apps can grab them. We've already seen that the old BSOD is gone, so hopefully this new course plotted by Metro will keep those frowny faces away.
