Windows 8 wholly embraces the modern app paradigm made popular by Apple and Google. Sure, "app" is just a hipper way of saying "application," and Windows has always had those. But face it, most users now associate the word "app" with mobile devices and the corresponding ability to instantly download and run a wide range of software. Windows 8 and the new Windows Store will no doubt stock the games and other fun stuff favored by consumers, but it also has the chance to apply the app-centric mindset to real business tools. That includes services with crossover appeal such as Skype for Windows 8, as well as business-specific platforms like Lync and Sharepoint (which will have its own app ecosystem for Sharepoint 2013).
