The thing I'm most excited for is Google Home. We'll see how good it is vs Echo. From what I've read so far, it doesn't seem like it'll be nearly as good which is a shame.
I probably won't get a Pixel phone this year, the 6P is still doing just fine for me which is awesome. My Galaxy S4 was a POS and I was in dire need for a new phone by the end of 1 year of use. I literally had to carry around an external battery otherwise the phone would die in a matter of 4-5hrs.
