Just bought a Pixel 2 for £440 (Currys clearing down their inventory I suspect) to replace my wife's borked S6.
I use a Pixel 2 as a work phone and its really good (i.e. it does all that I need to and doesn't do anything that annoys me) so I thought I would get her one to match.
Much as I loved samsung phones in the past, not very happy paying £6-700 for a phone.
Pixel 3? Don't see any reason to wait for it.
