Ah yeah thanks, not sure why I thought it was refurbished. So would you say the one below isn't worth the extra £100? The only advantage I can see is that it has more RAM, but with the Lenovo one you can install more (not done this before, but hopefully it's easy).

EDIT: Or this other one from Currys - again, not much difference apart from Intel and more RAM.
