Apple iOS 6 compare

The transition to Apple Maps is rough, but new features and a ton of tiny tweaks make iOS 6 a must-have update.

You won't be left too far behind without it, but Android 4.1 Jelly Bean is a worthy update that brings improved voice search, notifications, and sharing.

Windows Phone 8 is absolutely worth using, especially if you enjoy a simpler, bolder interface. However, if you need a robust app selection now, stick with the more fully formed Android and iOS.

Chrome OS struggles with the delineation between apps and Web sites, even though they are fast growing together. Great for students and casual home use, the day is coming when it'll be competitive, but it's not yet a replacement for a more mature OS.

Microsoft makes an aggressive, forward-thinking, and bold statement for the future of PCs with Windows 8, and vast security and speed improvements more than justify the $40 upgrade price.
