Mac OS X 10.9 Mavericks

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

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.

Ubuntu Touch

The new Ubuntu Touch operating system for phones and tablets blows away rivals Firefox OS and Tizen -- and it may even be better than iOS and Android.

Tizen OS

In an early demo of Tizen OS on a Samsung phone, the new OS looks a lot like Android -- and is clearly a long way from prime time.

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.

Google Chrome OS

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 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.

Editors' Choice

OS X Mountain Lion

When you see what you get for your money, Mountain Lion surely qualifies as the best value upgrade ever. The built-in social networking tools and the greater organisation afforded by Notification Center are worth the money on their own. The fact you also get native dictation tools, iCloud Document Library and more glosses an already compelling proposition.

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.

Microsoft Windows 7

Windows 7 is more than what Vista should have been, it's where Microsoft needed to go. How much damage Vista did and whether Windows 7 is enough for people to finally abandon Windows XP are questions that nobody has the answers to right now.

Mac OS X 10.5 Leopard

The grace of Leopard's interface enhancements makes productivity more pleasurable with a Mac, as more than 300 functional and fun features top off this update.

Apple Mac OS X 10.4

Though its new user features have mixed appeal, Tiger's technological changes and speed improvements make this an enticing upgrade, especially for those who passed on Panther.

Windows Vista Home Basic

Windows Vista Home Basic is essentially warmed-over Windows XP, Windows XP SP3. If you're currently happy with Windows XP SP2, we see no compelling reason to upgrade. On the other hand, if you need a new computer right now, Windows Vista is stable enough for everyday use.

Windows Vista Home Premium

Windows Vista Home Premium is essentially warmed-over Windows XP Home Edition. If you're currently happy with Windows XP SP2, we see no compelling reason to upgrade. On the other hand, if you need a new computer right now, Windows Vista Home Premium is stable enough for everyday use.

Windows Vista Business

Windows Vista Business is essentially warmed-over Windows XP. If you're currently happy with Windows XP SP2, we see no compelling reason to upgrade. On the other hand, if you need a new computer right now, Windows Vista is stable enough for everyday use.

Apple Mac OS 10.4.6 Tiger

Though its new user features have mixed appeal, Tiger's technological changes and speed improvements make this an enticing upgrade, especially for those who passed on Panther.

Mac OS X 10.4 Tiger

Due in mid-2005, Apple's new Mac OS X 10.4 promises more than 200 features.

Microsoft Windows XP Media Center Edition 2005

Media Center Edition 2005 is the best desktop DVR app out there, but it's not yet ready to play hub for your digital home.
