Specs
"While there were positive aspects of the notebook, there were also many negative traits. This resulted in a score of only 80 percent. For 699 Euro (~$875), the IdeaPad Z580 offers a solid notebook for a less-than-demanding consumer. We consider this notebook to be comparable to other notebooks from its class and price range." --That's assuming a price of £570 - at £450 it's good value for money.
Above average specs at a good price.
£450 with £25 Dabs voucher + £75 cashback from Lenovo - not exactly the same model but some useful info in this thread.
