By now, you will have heard at least something about Windows 10, the next iteration of Microsoft's OS that aims to create a unified experience across all the devices it'll eventually inhabit: everything from PCs and laptops to tablets and phones. Microsoft already released several preview builds for computers, and now the first Windows 10 Technical Preview is available for phones. You're highly unlikely to want to install this buggy early build on your daily driver, but don't sweat it. I've got just the phone for the job: a Lumia 630, which happens to be one of the few compatible devices at the moment. So let's take a look at what's new, and what's still to come.
The new stuff
A major part of the Windows 10 design philosophy rests on the idea of a cohesive design, so that the user experience feels familiar, no matter the size of the screen. Thankfully, this ethos has had little impact on mobiles, at least for now -- and from what we've seen already, a grand visual overhaul doesn't seem likely. Live Tiles still populate the home screen just as they did in Windows Phone 8.1. And that's great, since Live Tiles are by far the best thing about Windows Phone, especially after the slick addition of folder support.
