nokia has supported symbian for the last eight years (10 if you count back to the original symbian deal with psion). apps developed for s60 then work (mostly) now.

the n900 was never expected to be a success, it was a niche product by a niche team in nokia. now olli-pekka and the rest of the nokia board are in a dilemma: they have invested hundreds of millions into s60v5 and it's a dud. they have invested nothing in maemo and it's great. instituitional inertia is very strong.

assuming nokia's board makes the correct decision, maemo has a decade of support ahead of it. i love the n900, and must put my trust in the finns to do the right thing.
