I was going to post this from another merchant, but Dabs have it slightly cheaper here.
£379.99 after cash back direct from Toshiba. They come with a voucher in the box for claiming, you just have to make the purchase before Jan 31st.
2GB RAM (single chip, takes up to 8GB Max)
250GB Hard Drive
Vista Business/XP Downgrade/7 Upgrade
There are a couple of negatives to this thing as far as I can see: sub-3-hour battery life, 1280x800 screen, doesn't have 802.11n wireless.
For the money though this is excellent. Toshibas are great laptops - not as pretty as Sony, Asus, Apple - but very solid machines.
