many people wont like this, but here's the deal.
Symbian is a fat and outdated platform that just cant evolve, updating symbian reminds me of how RIM tries to make BB OS look like a modern OS, although its one of the most primitive systems in terms of capabilities.
Maemo was extremely raw, and we all loved it, I'm surprised that there are 1000s of nokia employees actually angry why Nokia abandoned MeeGo while very few of them actually cared and developed Maemo and MeeGo during their finest hours, Maemo was living because of the great people here who dedicated their personal time and effort to bring endless functionality that many salaried workers failed to develop.
I'm not sure of what happens inside the company, maybe there are wonderful ideas and crazy applications that are trapped within the R&D department.
Nokia realized that true open source is not the best option for mainstream market, and mainstream market is what matters, you cant control and manage an eco-system when everything is truely open (please don't argue that Android is open).
I just hope that MeeGo will survive and that there will be a MeeGo phone this year, even if it's an exact match of the N900 with a faster hardware.
