Looks like the Moto G has officially taken the Nexus 4′s spot on the Play Store. The LTE-deficient G can currently be purchased on Google Play for $180 for 8GB, or $200 for 16GB. Keep in mind this is the GSM model, meaning it should work just fine on T-Mobile or AT&T, sans LTE (sorry, Sprint/Verizon).
While carrier-branded Moto Gs were already running a pretty darn near stock Android experience, this version has the added benefit of updates directly from Motorola/Google, where it already kicks things off with the latest Android 4.4 KitKat. Link below for those looking to purchase.
