Just found in HP UK official site. Go to the business laptop section, select ultralight, and you can find HP 2140. select the cheapest model, 314 ex VAT, when check out, enter "HPQUIDCO" and the price will be reduced by 10%. that means 324 for this amazing netbook. PLUS if you use quidco you will earn another 3%, 9.42 quids. therefore in total you pay 314 for this one. I don't think you can get this cheaper anywhere in UK. order before 31 MARCH 2009 and get free delivery. Also note that you have to wait about 2 weeks for delivery.
vocher code also applies to all business laptops.
