So being willing to subject myself to loosing causes, I did some looking around on the google support forum thread for the WiFi issue. While I don't want to start a flame war or get into a back-and-forth with those who mandate that you don't get one of these, I thought I would add some to the discussion in general.
Before I begin, I should say that I am, and have been, sympathetic to the issue and believe there is some problem here for Google to address.
So first off, there continue to be people who claim their Pixel C is as good as or better than other tablets when it comes to WiFi. That's an important thing to consider since people with problems are more likely to post than are people without problems. In my mini analysis, I find that these are not all folks with an ax to grind and they are not all folks who have failed to do some testing.
WiFi issues can be notoriously hard to get to the bottom of over a forum to begin with due largely to the diversity of hardware, firmware, and settings in use. Still many of those reporting problems purport to have conducted a side-by-side comparison of performance with other tablets and phones. I wouldn't call many of the reports from people with problems or people without problems, scientific--in other words, troubleshooting is a science and many are responding with more emotion than raw fact. That always makes me more suspicious because I, perhaps cynically, believe that some things on the internet come from those with agendas--and they are usually the ones who start shouting first. It is also far too easy to loose all perspective on the intertubes.
This is a frustrating issue for those with the problem, but would you still be beating up the forums if you had this problem? Or would you return it and move on? I'm not asking people to justify themselves, I would be unhappy also. Further, as I said up-front, I think Google has an issue it needs to address. But consider the question for yourself and decide for yourself.
So I place in your capable hands, the link to the support forum thread with the admonition to consider all sides equally and don't get all caught-up in the emotion. For my part, I'm buying one in a month or two.
