MojoKid writes "Despite the fact that I've been using Windows 8 for the past three weeks, I somehow managed to overlook a rather stark feature in the OS: ads. No, we're not talking about ads cluttering up the desktop or login screen (thankfully), but rather ads that can be found inside of some Modern UI apps that Windows ships with. That includes Finance, Weather, Travel, News and so forth. On previous mobile platforms, such as iOS and Android, seeing ads inside of free apps hasn't been uncommon. It's a way for the developer to get paid while allowing the user to have the app for free. However, while people can expect ads in a free app, no one expects ads in a piece of software that they just paid good money for."
