I received my 6P last Wednesday. The last time I bought on issue day was the Bionic, which was a horrible mistake. The only bad thing about the 6P is the very weak vibrate motor. I don't know why some manufacturers do that. Otherwise I'm very glad I made the purchase.
My previous 7 phones were Motorolas. The last three or four were purchased at full price, and I was buying a new one every year. Needless to say I'm partial to Motos. However I would suggest to anyone considering a Pure to visit Motorola's forum.
There are many problems reported with crackling or popping noises in the audio. There were also some complaints pertaining to battery life, although that is a variable that is quite different among users. The other big problem is Motorola having delivery problems. There are many who have gotten notices of shipment only to find out the phone isn't assembled yet. There are other concerns also that I won't detail here.
I am lucky in that I am able to choose what I think is the best purchase other than being based on cost. This is my second Nexus and I see myself staying with the line in the future.....hopefully. And of course here is my disclaimer of "this is strictly my opinion".
