I posted the white version of this a while ago, but that's now gone up to £265.99 - amazon really do seem to change their prices on a daily basis with no discernible logic to it.
Anyway, this time it's the black version which is down to £249.99 - again the lowest price for this I've ever seen which includes free delivery to home - PC World sometimes matches it but you have to reserve to pick up in store which is going to cost you petrol, taxi or even bus fare!
Some people claimed that Tesco had it cheaper but I'm pretty sure that wasn't this version, which is the 901 with Windows XP.
So if you wanted the black version last time, here's your chance.
Not sure how to post an image, sorry.
