Acer Aspire One A110ab is only £172.99 (+£1.99 P&P) at CDiscount (can be paid in 3 installments of £57.66), and there's a 15% REFUND (account credit) in January. Works out at only £151.43 after the VAT refund!
Also, get 4% quidco too - an extra £6.06 back! Deal works out at only £145.37 if you have quidco! Bargain! Only £1 extra for next day delivery too!!
I have one of these, and paid nearly £200 for it, but couldn't live without it!! :)
