I have received an email from MPD saying the following....

" Hi,

Delivery of Nokia N900 stock into our Nokia stores has unfortunately been delayed by two weeks to w/c 16th November. The delivery when it arrives will be the first N900 stock in the UK and orders will be dispatched on a first ordered, first serve, basis directly from our Nokia stores. For those of you that have already pre-ordered and are expecting dispatch on the 30th October as previously advertised, please accept our sincere apologies and be assured that you are top of the dispatch list for a new Nokia N900. We have already seen working samples of the N900 and can assure you that it does exist and it will be very much worth the wait!"

This also matchs with the "mid november" statement from nokia.
So i suppose the 16th is the date to look forward to.
