One of our help desk guys has an N900, but apart from that I've not seen another one in the wild and as far as I know, noobmonkey is the next nearest N900 user to me.

92.3% of the population in Brighton seem to be iPhone users, although I have been showing off the N900 at every opportunity. I've found that the best way to shut an iPhone user up is to demonstrate the multitasking by opening up 7 or 8 applications then showing them the dashboard with all 7 or 8 apps still running. Never fails!
