I set one of these up for a work colleague and was pretty impressed by its versitility and speed. All these models have a 500GB + 8GB SSD Cache which boosts performance and I certainly noticed it when booting up and using office 2013 which is pretty slow to load on some of our older PC's.
He paid £400 which seems to be the going rate but found it for £350 at argos.
I was impressed by the build quality, screen clarity and thinness and the keyboard felt great to use.
Plenty of stock everywhere or can be delivered for £3.95
It comes with a fair bit of crapware but Ive seen a lot worse from the likes of HP!
