Windows Phone is discontinued, but sure as heck wasn't experimental. I've used it flawlessly since about 2011 with rock-solid stability and battery life.
What I meant was that I don't follow why does Nokia rock the boat with their choices of operating systems. They already have their own software running on the likes of the renowned 3310, so why not spend the engineering time to extend that instead of risking another platform becoming discontinued? That's what I would want to hear more about.
Ah, understood. I hope I didn't sound offended, just confused until I read your reply.
I agree that it is similar to Google in that they seem to hedge their bets too much (like how Google has two OS, two languages...etc etc). I would really like a third popular OS...there are so many out there, but with no steam (this, firefoxOS, sailfish...)
