Summary: We can remember when we first started using Windows 7; the start-up sequence wasn't that different from Vista, which in turn wasn't unlike versions of Windows that came before that. The chain of start-up screens could be long, sometimes taking more than a minute to complete. Depending on how slow the system was, it could have taken a while longer for the desktop to fully load. Here, booting Windows feels like turning on an Android tablet, or some other mobile device.
Pros: Works well on tablets, traditional PCs, Deep integration with SkyDrive, Xbox, Free music streaming, Improved multi-monitor support
Cons: Steep learning curve, Frustrating to use with a mouse, Limited selection in Windows Store
Excerpt: Microsoft's Windows 8 is a bold innovation, melding the worlds of tablets and PCs. Its excellent touch input, an app store, and better performance are compelling, but the changes will be too drastic for some and as a completely new product, a few rough edges remain.
Summary: Windows 8 represents a radical change for Microsoft, not just with its user interface, but in terms of the entire ecosystem of software and services. The new Modern style UI and Windows 8 apps provide an attractive, touch-friendly experience for tablet users. There are also some new features every Windows 8 user will love, regardless of whether they're using a slate, laptop or desktop.
Pros: Attractive touch-friendly interface, Tightly integrated with cloud, Compelling search feature, Fast boots, Slick Bing apps
Cons: Competing interfaces lead to confusion, Few Windows 8 apps for now, No Start menu
