Not very good at all. That's a previous generation i3 - soon to be 2 generations old - which is a huge step down on the integrated graphics. I struggle to see how it justifies its cost, being more expensive than many laptops with current generation CPUs. You could point out the 6GB of RAM, but RAM is dirt cheap - I picked up an extra 4GB to add to the 2GB already in my wife's laptop for £17. Screen is nothing special, ports are nothing special. HDD is on the larger side, but do you need 750GB? It doesn't even come with Win7 Pro, just Home Premium.
It looks like something that was once a top of the line, cutting edge device. But it's not discounted anywhere near enough to account for its age. You can get something with similar specs (last gen CPU, only 4GB RAM and 500GB HDD) for £338. While the Toshi is more stylish, I don't think it's £100 moreso. £350 and you get a current generation CPU.

(only 2 USB ports, but makes up for it with one being USB3.0)
£370 gets you a Toshiba (if brand names mean something to you) with a current gen CPU, 6GB RAM and 500GB.
