|Bottom line|| |
Windows RT is a strange beast. On the one hand, speed, security, and the best of Windows 8 make RT a pleasure to use. But app restrictions make Windows RT confusing, and the limited availability of apps undercuts the operating system's usefulness.
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.
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.
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.
