I found the most downloaded applications from maemo.org site - so many downloads - about 5 000 000 (5 miliions downloads) right now. This shows Maemo platform very popular!

I also think the poll option OVI Maps is not correct because it is pre-installed on the device, so no need to download it from the Ovi store, only for the existing devices, if it is compatible with the old devices...
