New information: the N900 will be the first ARM reference hardware platform for MeeGo. http://meego.com/community/blogs/val...owards-day-one If you wait a little more (PR 1.2 and Harmattan alpha SDK release) you will get more announcements and future plans. I'll do my best hunting for the Ovi Maps answer.
In the meantime I will help with the wiki page. Thanks Matan for starting it!
