Query: Buyer Beware!

Look up "Apple TV disappearing" on google or the Apple support site to see how many people are having issues with this product. It worked REALLY well until Apple upgraded to iTunes 8.0 after which it will NOT synch and has essentially become a brick. Apple has done nothing to resolve this issue even though it has been an ongoing problem. The wanted to charge $50 for a 30 day "troubleshooting" period with one of their specialists. (the $50 charge is because he "took the time to learn about the product".) The product became useless overnight. I have not been able to use it for 6 months. Even if they do fix this issue, the next upgrade may mess it up again - another $50? This could get expensive....
