The NexusNexus 6 is the reason I'm not getting the Nexus 6p. That phone was a real nightmare. First off, actually buying the thing was impossible for the first few months (good job google).
Second, within an hour of buying it I was regretting the purchase. Stuttering, lag, missed touches were my experience out of the box.
Third, despite what the reviews said that camera was bad. Really slow to focus. Even slower to release the shutter. Just bad. Macro, anything closer than about 18 inches or so, was impossible to focus on.
IMO, Nexii has a really strong reality distortion field. At least in the past they were cheap so it makes the shortcomings a lot easier to accept. With prices being the way they are I'd rather spend the extra money and get something more polished and just all around better.
