I bought a Sony Vaio computer from Best Buy a little over a month ago and have had major issues with it. I had to take one back and exchanged it for another Vaio because I liked the features of the computer. I had the first computer less than a week and had problems with windows 8's compatibility with the hardware. After I exchanged the computer I had hardware issues with the new Sony and spent approximately 4 hours on the phone with Sony tech support to resolve the issue. After I was able to get the problem resolved, about two weeks later I had the same issue again and was unable to use the computer, which I needed to complete my work. I called Sony and was told that the wait time was 73 minutes. That would indicate to me that I wasn't the only customer who was having problems with the computer.
I took the computer back to Best Buy and even tho it was past the 30 return/exchange period, the manager allowed me to get rid of the piece of crap and exchange it for another computer, which was of course not a Sony. I was happy that they were also able to transfer all my files to the new computer for me, since I had done this twice already.
I was more than happy with the level of service I received.
