anecdotal evidence at best. If that's what you want, here's my experience, the small minority are often the most vocal about their devices. Look no further than the maemo community here. Most are happy about their devices and often vote for their device when given a chance and sometimes attack those who disagree. Remember the FoneArena vote?

It's no different for the WP7 minority, after all you must have strongly liked something about these phones to join the small minority (more often than not brand affiliation or view, though not always), so often views on a device from a minority are cemented before they even receive the phone and continue on long after. These people are still the minority though. A vocal minority.

Amazon review ratings are the same. I remember the Lumia 900 reviews coming in on the day of release. Nobody and I mean nobody mentioned the data connection bug which was quite a prevalent problem. I remember the one person who did and reviewed it 3 stars was attacked by countless other users for having an opinion. What made it worse for amazon reviews? I believe they are weighted. So even if their review had truth to it it gets drowned out by people who click "did not find this review helpful" while rating up the reviews that just say "awesome" 5*.
