Came across this at Currys, a refurbished Toshiba with an Intel Core i3-330M processor (faster than Pentium Dual Core, and uses less energy => better battery life?), 4GB of RAM, and 320GB hard disk drive.
Use voucher QUIDC5 for 5% off the original price tag of £399.99.
Also get 3% QUIDCO for a final price of £368.80 - an extremely good deal for this spec I think.
Other specs include webcam, media card reader, HDMI output.
It's refurbished, but with a 12m warranty - if it runs for a year without issues, it's as good as new in my books.
Only available for home delivery.
