As promised, Google’s Nexus 4 and Nexus 10 both went on sale this morning. Both devices have proven to be pretty popular, but the Nexus 4 may just be Google’s most popular device yet.

The Next Web reports that the Nexus 4 sold out on the Google Play store in about 50 minutes this morning. If you check the store, both the 8GB and 16GB variants are sold out. Customers who missed out can enter their email address so they’ll be the first to know when it’s back in stock.

The Nexus 4 isn’t just doing well in the US. There are reports that that the new smartphone has sold out in the UK and in Germany. Germany was by far the most impressive with its initial allotment selling out in about 15 minutes.

The Nexus 10, Google’s new 10-inch tablet, is doing pretty well for itself too. The 16GB variant is still in stock, but the 32GB variant sold out this morning. The Next Web reports that the Nexus 10 has also sold out in the UK.

The rate at which Nexus devices sell out proves that Google is doing something right. It’s probably the combination of solid hardware with low prices, but the devices being equipped with stock Android may have something to do with it too. There’s something to be said about having a pure experience, and Android on Nexus devices provide that kind of experience.
