I don't want the N900 to be too mainstream, honestly.

Until the security platform is rolled out in Maemo 6, protecting "average users" from themselves, it is best that Maemo is kept somewhat niche. Most geeks won't let their phone be taken over by a trojan, but can you imagine the chaos if the iPhone users were to switch to Maemo en masse? Suddenly, Maemo would look very interesting to criminals.

It would only take one clever, nasty criminal with bad intentions to start spreading a very serious "phone virus" that silently called Nigeria in the background and e-mailed all your passwords (are they still stored as plaintext in gconf?) to Russia...

EDIT: No prejudice meant. Some of my best friends are Russian Nigerians. I'm even helping this nice Nigerian widow lady transfer her husband's money out of the country through my bank account!
