When I decided to get rid of my minimal phone (LP2) - and go with GOS on a pixel device - I had to decide whether to go with the P6P or wait a couple months for the P7.
When I was able to get a great deal on the P6P (< $550 - new) it seemed the way to go.
Now - seeing the specs on the P7 series - glad I didn't wait.
Seems that whether an iphone or an Android phone - the changes are minimal... very few features or even hardware enhancements that would entice an upgrade unless moving from an older EOL device.
One reviewer of the P7 line said that the P6 line was a leap but the P7 is a small hop. Many IOS fanboys are even more critical on the 14 models.
Thankfully - GOS is here and I can enjoy 4+ more years on my P6p....
