Windows 8: The official review

Love it or hate it, Windows 8 is ushering in a new era of cloud-connected Microsoft services, a unified user interface, and more-robust social media interaction. Younger users may find Windows 8 more attractive than some old-school computer users will. It's a risk that Microsoft needed to take to try to remain relevant in today's connected, mobile world. Only time will tell whether it's the right risk at the right time.

Windows 8 isn't for everyone. If you're mostly a desktop PC user comfortable with Windows 7, upgrading to Windows 8 is probably not worthwhile. If you're a mobile user who needs easy access to the complete Microsoft ecosystem, including SkyDrive, Windows 8 is definitely a good fit. If your needs lie somewhere between those two extremes, give Windows 8 a close look; the cost is low, but you'll need to learn your way around the new Start screen and make sure that your existing software runs well in the new OS.
