I think the N900 is a few weeks away still. My-Symbian reports they are in the process of adding 2 more gigs for apps before shipping. My guess is they are simply displacing some of the 32gb of onboard memory, but regardless, this means there are currently no devices on route to consumers.

If they were actually adding 2gbs more memory to the device, that would obviously be a while before shipping- a long while.
