The new version of Android is finally here, and its biggest feature is a new stage for an old favorite. Google Now is getting more limelight than ever, and that's fantastic. But even better, even folks with older handsets will (theoretically) be able to get in on the fun.
With the update to 4.4, the ability to jump to Google Now by saying "OK Google" comes to vanilla Android, though only for the Nexus 5 right now. Google Now is also making an appearance as an actual page on the homescreen, through the addition of a new Nexus 5 launcher. It's unclear how much of this will come to other phones but hopefully all the parts will that don't require specialized hardware. (Update: Yup the "OK Google" is only for the Nexus 5, in part because you need chip-level hardware to support it. But expect that to be a feature in a lot more Android phones to come, definitely any that are repping a Snapdragon 800.)
And it's not just the same Google Now you've had all year; Google says the prescient service is about to get some updates for even more new cards that will try to guess what you want before you're even thinking it. That'll sure be handy for when that smartwatch comes out
There are also a couple of app updates. We heard what was coming for Hangouts a few days ago
And while KitKat is launching with the Nexus 5, and shortly rolling out to other Nexus and Google Play Edition devices, folks with older handsets have stuff to get excited about too. This is the boring, but important crux of the KitKat upgrade: with a wealth of under-the-hood improvements, KitKat is actually reducing the toll the OS takes on a phone's guts. Thanks to a reduction in KitKat's footprint it can run "comfortably" on devices with as low as 512MB of RAM, so KitKat won't just be for the high-grade device elite once it starts trickling down through carriers. Maybe we can finally get some Android unity, though that's the promise every time around. This time there's no real technical reason it shouldn't happen though as long as carriers and their skins
Android 4.4, KitKat, which comes on Nexus 5, will also soon be available on Nexus 4, 7, 10, the Samsung Galaxy S4 and HTC One Google Play edition devices in the coming weeks, and hopefully everyone else in the not-to-distant future.
