Agreed, that's one of the most important things.

However, I thought karan was talking about the Google ecosystem, because all of those tie into Android. Android is just a vessel, and on its own its not too special. In fact, if you try running barebones AOSP with no Google ties, it becomes a poor experience.

So if Nokia wants to dethrone Android, but keep Google's services that's an entirely different question and scenario. For example:

- Use Linux kernel, Qt framework, and Kangal UI
- Make Nokia N9 like device, just re-freshed and not sucky
- Use OVI services, but polish them up
- Use HERE Maps, it might need some updating
- Have native apps for YouTube, Netflix, Vimeo, Twitch, Vine etc
- Have native apps for Facebook, Twitter, Instagram, Snapchat, Meerkat etc
- Have a native cloud storing facility to sync Contacts, Alarms, Calendar, Memos, Settings etc etc
- Have a rock-solid email solution, and one that caters for the big ones MS, Google, Yahoo
- Allow the user to search through Google, Bing, DuckDuckGo (and maybe Wolfram Alpha)
- Use Miracast for TV connectivity
- Use a translating engine from a third-party like Google
- Make sure there are competent primary native first party applications such as:
Phone, Messages, Contacts, (again Browser), Camera, Gallery, Voice Recorder, Calculator, Memo, Calendar, Alarm, Clock, Music Player, Video Player.
- Also make sure there are competent secondary native first party applications such as:
Flashlight, Compass, Thermometer, Barcode scanner, Document Scanner, PDF Reader, Comic/eBook Reader (dont judge), Quick Photo/Video editor
- And finally port over the top 100 iOS Apps, top 100 iOS games, top 100 Android Apps, and top 100 Android games.

Then sure.
I mean its not like Jolla is having a problem with this. Or that Blackberry is having a problem with this. Or that even Windows Phone and Windows 8 is having a problem with this. (sarcasm).

But yeah, those are the milestones.
They aren't impossible, its just difficult and a long procedure.
And had Nokia taken the initiative, ditched Symbian to focus on MeeGo, and not whored itself out to Windows.... this would've been long history. I mean they shipped the Nokia N9 in September 2011. They should've launched it way back in mid-2010 and also acquired Palm. But even so, launching it in 2011 by themselves, they could've caught upto Android/iOS in 3-4 years... they would've been broke yes.... but they would've caught up. And they could be sharing a decent marketshare today, slowly making up their investment, and be quite competent. In fact, Windows would probably be in a better shape too since they would've purchased RIM for a dime and strengthen their portfolio.

In fact, the biggest loser here is actually SONY.
They can actually produce processors, displays, and cameras... and own the industry in terms of Music, Videos and Games. The fact that they didn't go the route of MeeGo is their biggest downside and loss.

Siri runs on Wolfram Alpha.
Third-party would be fine, its still a task that shouldn't be underestimated. This is the reason why Google produces so little profits, yet is overvalued so highly. They own ecosystems all over the world, all over the industry. If suddenly Google shutdown everything, 70% of the internet would disappear and 80% of phones would become paper-weights.
Thanks, I bleach myself and shower in parfum for you honey.
