They have the open source Maemo platform, which they’re already using in moderately successful devices such as the N800.
In January, they acquired Trolltech, whose technologies (which power KDE) are more-or-less competitors to those already in the Maemo platform (those used by GNOME). Seems like an odd position already.
And only yesterday, they announce that they are acquiring Symbian and handing Symbian OS et al over to the newly-formed Symbian Foundation, i.e. they’re opening up the source code.
You know the grey goo doomsday scenario? Seems like Nokia is just swallowing up as much stuff as it can and turning it into open source goo.
While I guess it’s a good day for software freedom in general, I can’t help but feel a little dejected by the lack of focus on and commitment to Maemo by Nokia. But with OHA Android, LiMo and OpenMoko all looking to win the hearts of developers and consumers alike, perhaps Nokia is right to feel the need to have three independent, (if incompatible) software stacks in its arsenal.
