If you need any proof that the Nexus line is no longer a top priority for Google, look no further than the special edition of the Samsung Galaxy S4 headed for the Google Play Store. The $649 device is by no means price competitive with the $299 Nexus 4, but it gives Google a cutting edge device while the company finishes up the Nexus 5 in time for the fall. Or maybe it doesn't need to. The S4 will not only have Google's latest software and services — sans TouchWiz skin — but it will support LTE on both AT&T and T-Mobile. Assuming the price comes down over time, why bother with a Nexus 5 at all?
