Android Pie

Android 9.0 is already on some Android phones. Here's what you can expect when it comes to yours.

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.

Apple iOS 8.1

With the latest version of iOS and an NFC-equipped iPhone, you'll finally be able to pay for transactions with Apple Pay.

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.

Mac OS X 10.11 El Capitan

If you own a Mac, you'll want El Capitan. This update simplifies the Mac experience, improving the tools you already use while promising improved performance to come.

Microsoft Windows Me

Millennium is a great face-lift for Windows 98, but it's not a necessary upgrade. If you have technical difficulties or work with pictures or music, try the new OS. But if you're happy with Windows 98, stick with it.

Android Wear 2.0

With lots of new features, the LG Watch Sport and Style are the first to use the new software -- and it's promising.

Apple iOS 10

iOS 10 serves up plenty of useful quality of life improvements, but a few rough edges keep it from shining too brightly.

Apple macOS High Sierra

Unless you're really into Photos or have installed the iOS 11 beta, there's no FOMO by passing on the public beta of Apple's latest OS.

Mac OS X 10.10 Yosemite

From new Continuity features to smaller, useful tweaks across core apps, Mac OS X Yosemite is a must download for Mac users.

Microsoft Windows 8.1 Update

With new functionality for the Start button and separate experiences for desktop and tablet users, the Windows 8.1 update finally gives people what they want.

Google Android 6.0 Marshmallow

Android 6.0 Marshmallow is out now. This is everything you need to know about Google's mobile operating system update.

Google Android L

Google gives us a preview of the future of its mobile operating system.

Mac OS X 10.2 Jaguar

Take a good, hard look at Mac OS X 10.2 if you're adding a Mac to a Windows network--Jaguar's new tools can't be beat. But home users, beware the $129 upgrade price if you're not looking for networking options.

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.

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.

Apple iOS 9

If you own a recent Apple device, you'll want to make the jump to iOS 9: Better battery life, improved native apps and multitasking prowess on the latest iPad make this upgrade a no-brainer.

Mac OS X 10.4 Tiger

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