A slightly technical side note. Flash on the N900 (Maemo) is AFAIK closer (=based on) the desktop version of Flash. All the others require a radically different approach (one of the reasons why Adobe specifically ports things to Android, BB and whoever). So from Adobe's pont of view, there isn't really much to announce for Maemo, it's a NPAPI based Linux build. As in, not much more than they want to announce things specifically for Ubuntu, Fedora, etc. Now comes the sticky point of the porting kit. Hey, here's this Linux porting kit ! Cool. But... does it support PowerVR hardware/drivers for the acceleration, 'cause its not that common on PCs ? Does it support ARM for non-desktop builds ? There can be many hidden gotchas Nokians could be forced to work around before it actually works on the N900 (we know from comments on the N800 that they ARE adding in Maemo-specific patches). Now you ask, if that is the case, why not fire back a volley at Adobe and say 'hey, its not that simple', but a) Nokia employs underpromise approach and/or b) They do not want to endanger future cooperation with Adobe on MeeGo/Symbian by bickering over a deprecated platform. On another side note, while we are speculating, one could say the no commercial support for MeeGo announcement would have been a good spot for Flash, too. It's always better dealing with 1 backlash instead of 2.

Considering the license requirements of Flash 9, you'll never see that source code (not more than you see Flash 9 source code for Linux). Even Flash 10.1 is just in baby steps phase in this regard.
