I got a stonking deal on my 8 via carphonewarehouse + enhanced cashback + topcashback. Took some pissing about with the tradein and in the end they paid it twice so I forgave them. Keep an eye on hotukdeals.
That being said I'm not super impressed, I had a 4 year old Oppo before that was holding up very well and was somehow more polished and less buggy than my new pixel which seems to get confused with the gestures (i.e pulling the running app selector up works 50/50 and going back often clashes with app's back gesture). The dialler is dreadful too and I often struggle to be able to hang up and it suggests ancient never used contacts over people I call daily, the camera often opens unfocused (although that seems to have been resolved as of late). It's also started flag a warning about having moisture/debris in the USB port too and were it not for the fact it was near free once all the deals stacked I'd have been pretty disappointed.
In short it's not quite the smooth native experience I was hoping for but then Google has gone to shit all around so no big surprise. Based on my experience with the 8 I certainly wouldn't be in a hurry to chuck the big money down for a 9 that's for sure.
