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.

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.
