Google recently unveiled the much leaked Nexus 5 and there weren't a lot of surprises. The Google flagship phone comes with a 5' 1080p display, the latest snapdragon 800 processor, the excellent LG G2 chassis with a super thin bezel, and finally, a decent camera sensor with optical image stabilization.
Besides the top of the line hardware specs, it's also the first device with Google's latest and greatest Android 4.4 KitKat OS, which brings a plethora of new features, under the hood optimizations and UX fixes. And if all these weren't tempting enough, the attractive off contract unlocked prices $349 (16 GB) and $399 (32 GB), make it the best value smartphone on the market. It also performs respectably and in some benchmarks outperforms comparable models from Samsung and HTC sell for $250-$350 more.
Now, if you already have a latest generation phone, be it an HTC one, Samsung Galaxy S3/Note3 or even a MotoX, there is probably no reason to change right now. They are all great devices and you should be getting a 4.4 update in future. If you are impatient, look out for a Cyanogen mod of KitKat soon. Wait and hust get the Nexus6 next year. For the rest, preorder one right now, if you can still find it in your nearest play store :)
