This has 1x1GB RAM, as opposed to 2x512MB, so quite cheap/easy to add another 1GB. Battery is 6 cell I believe.
Laptops Direct also have this at the same price, but even with Quidco it costs more as you need to buy an accessory to get free delivery.
I've been looking to buy a laptop for a while and quite like this. Similar spec. Toshiba/Asus seem to be £600+.
