It's a good price for the item but for me the poor battery life lets it down. The screen is a big bonus though so horses for courses. And yes I know it's the same basic spec as other cheaper netbooks but some people like Sony and are happy to pay the Sony premium.
Edit to say it was £399.99 which is far far too much!
