I had a launch PS2, and it worked perfect for about 5 years, then I had to clean it once. It still works perfect at it's new owners house. (after cleaning it)
I have a PS3, and I havent had a problem out of it.
My PSP hasnt had a problem either.
Really other than that, I dont have anything sony.
Sony stuff is just too expensive for my taste. My TV is a samsung, wich is made in partnership with Sony, so it could be called a sony I guess.
I also swear by Sony Cell phones. They are sturdy, well built, and work very well. I am useing a 4 year old sony cell phone that was free with contract (4 years ago) over a new 100$ phone with contract. (I went to my antique phone over it, becuase it sucked so much)
My wife has a sony phone, and the phone I 'want' is also a sony phone.
(this is because I have never had a problem with sony phones, they are damn near perfect, they are extremely well built, and have great sound quality, they are known worldwide for their speaker-phone, and the camera in them is second to none)
I think sony stuff is worth what you pay. You are very likely to know someone who had a problem with a PS2. 120million were sold worldwide, and millions are 6 years old.
Your just as likely to know someone who has smoked a 360. (I actually do not know anyone who lost their PS2 unless they destroyed it themselves, and I do know someone who lost a 360)
