Not sure why you say it is "vaporware" when now there has been three releases of the OS. Granted, it might not be ready for primetime for most users, but there is some obvious work being done and progress that can be measured by those willing to install it.

Personally, I have no interest in it until things reach a point where it would be more beneficial to have MeeGo on my N900 rather than Maemo. It may never reach that point, but then again, I'm pretty happy with the way Maemo performs for the most part right now. Going to MeeGo in the short term probably means that I'll lose a lot of the applications that I'm used to on Maemo, which will take time to replicate on MeeGo.
