Ok so I realise this will probably get some cold votes as it doesnt seem to be much upgraded than the nc10 netbook apart from battery life, ergonomics and sub woofer.
Cheapest I have seen though by some margin http://www.dealpond.com/prices/laptops/samsung-npn120ka03uk
Please post if you have seen cheaper elsewhere
