Maybe not cheap enough to be called a bargain, but I think you get your money's worth, especially with the 1Gb Geforce GT230m graphics card and P7450 processor. It is also a glossy, sexy black colour and has a multitouch track pad. Harmon Kardon speakers too. Oh, and its a Toshiba.
Use the £20 off voucher PIXUK091102 which was still active on 26 November, incorrectly expired. Possible Quidco too, about £14.50. Deselect the VIPIX loyalty card in order to drop the P&P to just £6.20.
So, £599 - £20 + £6.20 - £14.50 (Quidco) = about £571 pounds.
Bought one for my wife a week ago, arrived ok with UK plug. Actually dispatched in the UK by the company that owns PC World, Currys, and they are currently charging £699 for it.
And yes, Pixmania have a horrible, horrible track record of customer care. Buyer beware.
