n900

On May 25 2010, Nokia announced that future development for Maemo on the n900 would cease, although support for the n900 continues with release 1.2 of Maemo 5, and there are no official plans to port future developments of MeeGo or Harmattan for upstream Nokia devices to the n900, so the future of the n900 is unknown as of May 2010.[73] The developer community that has built up around the n900 has talked about working on community releases and support, in a similar way to what is found with Linux variants generally. Whilst this may be a workable solution for applications, which is open source, much of the software that interfaces with Nokia hardware is proprietary and closed source and relies on Nokia support in a way that would allow integration with unofficial developments.
