welcome to the thread, as of 19 december the laptop is now 11 months old. SO has less than one month warranty left. I have called sony and they pretty much could not be bothered helping out with such a short warranty time frame, and also me not having the receipt doesnt make it any easier (it was accidently dumped along with the box and manuals when I moved!)
The laptop is like new anyway so im sure there will be no worries with it. You can even come and check it out before you pay and if your not happy with it, dont feel pressured to buy because if it doesnt sell im happy to just keep it I have nothing to hide with the laptop.
