Oreo doubles down on the nuts and bolts -- and speed.

Apple iOS 11

Google Android Nougat

Mac OS X 10.4 Tiger

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

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 10.2 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 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 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.

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

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.

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.

Google Android L

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

Google Android TV

Google is taking yet another shot at a living room software platform with Android TV, which runs on the upcoming Android L platform.
