Yea, there are quite a few who have had good and bad experiences.
One thing that i have already seen mentioned at least once is that it is important to keep in mind, WHO would go online to look for places that talk about their systems crashing? People who have had their systems crash. For instance, when i have a problem with my computer, i look on websites where people talk about such things to look for help. Now, if one were to look at a forum called Computer Repair, they would quickly think, 'WOW, there are a LOT of computers breaking down! Why is that?' Well it's simple. Your looking at a forum where people go to talk about it! If you went to a regular forum, you'll hear about breaking computers a lot less. So when all you do is look in one spot, your view can become distorted. You must keep in mind the bigger picture. Which, in this case, you must realize and remember that there are no doubt TONS of 360 owners that don't even realize sites like this exist, nor do they know that so many x-box 360's have broken because theirs has worked fine since they got it. On the same hand, there are some people that have had nothing but breaking consoles since day one, and wish they knew of a place like this to come vent...but most of those people manage to find their way to places like this to talk about it.
Do you see and understand my point? With this in mind, i would say that the results of the poll are at least somewhat skewed to the negative side. I myself haven't had a single problem with my X-Box360 since i got it, and it's been put through...probably well over 1000 hours of use, with around 200-300 in Oblivion alone. Is there any way to find out how many hours your 360 has been turned on for? My house is like a community house in that people come over and play on my 360 all the time, and it's still kicking strong!
