EDITORS' TAKE

Nokia X Software Platform

Nokia sure tried hard to give us something new, but its mashup of Android, Windows Phone, and Asha gives its Nokia X phone limited powers and a nagging identity crisis.

As it's a free upgrade that gives you more apps, improved features across the board, and better performance, there is really no reason not to get Mavericks on your Mac.

Microsoft Windows 8.1
REVIEW

Microsoft Windows 8.1

If you're a dedicated Windows 8 hater, the update to Windows 8.1 isn't going to change your mind. For everyone else, this collection of tweaks, fixes, and new features is useful, but everything here should have shipped in the original version last year.

Firefox OS
EDITORS' TAKE

Firefox OS

Mozilla's mobile operating system, unveiled at Mobile World Congress, won't win over many iOS and Android faithful. But it's credible for low-budget feature-phone owners.

REVIEW

Microsoft Windows 8 Pro (Upgrade)

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.

Apple Mac OS X 10.6.3 Snow Leopard
REVIEW

Apple Mac OS X 10.6.3 Snow Leopard

Intel Mac users will like Snow Leopard's smartly designed interface enhancements, and its Exchange support is a must-have (especially with Outlook for Mac on the way). With a ton of technological improvements, Snow Leopard is worth the $29 upgrade fee.
