I would love to have a Nexus 6P, because I'm a long-time Nexus fanboy, I'll explain why. Ever since I got my first smartphone, the Samsung Droid Charge, I realized how important it was to have an OEM update the OS of the phone. The Droid Charge, for those who don't remember was released half a year after Gingerbread came out, but it still featured Froyo! What a joke! It also got Gingerbread a couple of weeks before Ice Cream Sandwich released, and it never got an update to ICS at all! Ever since then I have refused to trust any Android OEMs since they constantly release new devices but ignore their old still perfectly functioning devices. Google with Nexus is different. They update their devices much longer than anyone else and I love that.
I'm still rocking the 2013 Nexus 5, and while it runs great, I don't have the money for the Nexus 6P.
