I agree with the statement that "All you ever hear about online is bad 360 experiences, because those who have had good experiences have no reason to comment or complain."
That is why all the poles show something drastic like "30% Failure RATES!!"
It's because only people who have broken Xboxes are searching about it and find those polls. People like me, who have had an Xbox 360 for two years and have had NO problems at all, have no reason to search "RRoD" on Google and therefore do not add our results to the polls.
The real only flaw, and the reason some people receive multiple broken consoles, is because at first Microsoft would receive a broken unit, send out a pre-fixed one right away, then fix the broken unit and send it out to someone else. And often times since you were receiving refurbished units, the problems were not entirely fixed. Now that they are shipping out the newer sku's, and are actually doing a good job with repairs, the numbers have dropped drastically.
