The Sony is very good, but my HP is even better. A good 4hrs plus for the HP, but only 2hrs max from the Sony. Both well made and fast. Sony has the slightly fancier X-black high-contrast screen, but this is more prone to reflections.
I'd go for the HP first and the Sony as second choice. Both very good value for money, but the HP has the edge there too.
