Vaios are overpriced for what they are. It all depends if you want windows or osx really. Haswell processors are out now, mac should catch it up in a few years...
By the way, forgot to add earlier....if you really want a Windows laptop, look at ASUS instead of Sony. Far better made & better specs for the price. The two ASUS laptops I have owned now, not one has given me a problem....ever. I highly reccommend the brand & it's the ONLY laptop brand I will purchase now.
