With much riding on the new version of its marquee software, Microsoft opts for caution and says the Windows 10 rollout will come "in waves, slowly."
iPhone and iOS news
Nokia's Lumia 920 is heavy and thick, but if you want the most powerful, feature-rich Windows phone available, this is it.
With top specs and a striking design, HTC's Windows Phone 8X makes a smart choice for anyone ready to dive into the Windows Phone OS.
While its camera isn't best-in-class and Windows Phone's underwhelming app selection still stings, the elegant and sophisticated HTC One M8 is an enticing alternative to Nokia models.
A great example of a Windows-based smartphone and a killer option for what it costs, although there's still not quite enough going on with Windows Phone to pull people away from Android or iOS.
Although the Lumia 735 doesn't have the best camera, it's colourful, curvy and comfortable, has a good display and an affordable price -- all of which go a long way to making up for it.
The Nokia Lumia 810 makes for a practical smartphone choice, but if you're looking for something thin and light, the HTC Windows Phone 8X is one better option.
With its great display, brilliant camera and attractive, colourful design, the Nokia Lumia 930 has most of what you'd expect from a top-end Windows Phone device. It's battery lets it down though and with an unimpressive selection of apps still available from the Windows Phone store, a high-end Android device with a good camera will likely be a better option for many of you.
The Nokia Lumia 630 is a cheap, vibrant alternative to Android and its Windows Phone 8.1 software is easy to use. The app store is still a problem though -- if you like getting new releases when your Android and iOS-toting friends do, a budget Android phone like the Moto G is still the way to go.
Steer toward Nokia's Lumia 1320 for an affordable supersize phone you can rely on, but not before checking out Android rivals with fancier specs and comparable price tags.
