Nokia could not stick with a single platform, once their heirloom Symbian became inadequate they caved. Like the absolute majority of corporations, they did not understand platforms. Platforms require decade-long thinking, instead of "Q4 this year". N900 with its Maemo was pretty good phone. Too bad Nokia could not develop on the success. Then they have MeeGo and then the disastrous Windows Phone. MS had the same problem with Windows Mobile - Windows Phone 7 - Windows Phone 8. 15 years later, the Debian + Firefox + APT platform on which N900 was based is still alive and requires surprisingly few maintenance. If they went with it they will have a solid, hassle-free platform which could compete with early Android, especially as they could easily make it run Android apps as well.
