If you're interested, quidco are currently doing 20% cashback on the N900 direct from nokia, bringing it to £400 sim free and actually posted next day. Not as cheap as some got it for, but still cheaper than any other (not nokia/mpd) shops are offering, and they aren't even expecting stock until january, so it's doubtful there will be a big drop early in the new year. I ordered it on that deal yesterday evening and it was posted today, and the £100 cashback is tracked in quidco. Much better than MPD who refused to honour the T-mobile contract I ordered in september and suggested I get one of their current vodafone contracts, which are £70 more expensive even if you factor in £20 a month for the extra six months you're locked into the contract. I've also got a 'giffgaff' (O2) PAYG sim which has unlimited free data until may, which is a pretty good deal.
