If you don't mind working with a refurbished product (albeit one which comes with a year warranty) and have no qualms using AMD's alternative to the Intel Atom processor, the E-series APU.
Then check out the Lenovo G585 laptop on sale at Argos via the latter's eBay outlet. At less than £200 (plus £3.95 for P&P), this is an enticing proposal especially as it includes 199 Nectar points.
The device runs on an unknown E-series AMD CPU, possibly an E2-1300 clocked at 1.5GHz with an AMD Radeon HD6310 GPU. It includes Lenovo's Veriface's face recognition, 4GB of RAM, a 1TB hard disk drive, a DVD writer, a 15.6in 1,366 x 768 pixel display, Windows 8, an Ethernet port, three USB ports, HDMI connector, a webcam and a weight of 2.6Kg.
All in all, it is a fairly standard laptop although its price is likely to get heads turning given the fact the copy of Windows 8 and the hard disk drive have likely cost more than £100 by themselves. This would serve someone who wants an affordable computer with a massive storage capacity.
Bear in mind though that the E-Series APU that powers it is a rather old and slow processor which is unlikely to sustain the strain of say, full HD display.
