A few days back, it was revealed that Nexus 6P will cost $500 but will be available in Europe for €650. Now, we need to lay down after seeing the prices for Nexus 5X i.e $380 per phone. Google store has put up the pricing for Nexus 5X and the 16 GB model at €480, which is the price for the 16 GB phone.
If you want to purchase a phone with more storage you should go with the €500+ versions. In the UK, the 16 GB model is available for £340. While the Nexus 6P is not a bad phone, the Nexus 5X on the other hand is not much upgradable over the Nexus 5.
