This just in from Nokia, in response to our query. "Maemo on Nokia N900 is not upgradeable to MeeGo. The first MeeGo device is targeted to be released during the second half of 2010. However, applications written for Moblin or Maemo Qt APIs will run on MeeGo."
That's probably the first official statement we've heard from the Finnish phone-maker regarding the upgradeability of the N900, which runs on Maemo 5, to MeeGo. The open-source Linux operating system which merges Maemo 6 and Moblin 2 was jointly announced by Nokia and Intel last month.
This latest development shatters any hope raised by a March 3 blog post by Valtteri Halla from the Technical Steering Group of MeeGo that the N900 may be in line for an upgrade to MeeGo. He wrote then that the "first and very raw baseline to a source and binary repository to build MeeGo trunk on Intel ATOM boards and Nokia N900" is targeted to be available "by the end of this month".
Well, we know now the N900 will not be upgraded to MeeGo, not officially anyway. That said, the target audience of the N900 probably isn't made up of your average Joe, and given some programming skills, we're sure they should be able to make the codes as good as an official upgrade.
