1. It's said that they'll be supporting it until 2014; but, not sure how true.
What important is they fix all the major bug/issues, and the phone is stable for daily use.
The main issue is not much apps. 2. There's much lesser app for MeeGp Harmattan compared with Symbian.
This is the main drawback for MeeGo Harmattan, lack of apps. 3. Processor isn't really important; What's important is how the device performs.
If you have QUAD CORE but the device lags or performs sluggish, what's the point of having QUAD CORE? In the end it's just for "syok sendiri" to know the phone got QUAD CORE.
As long everything performs smooth, it's good; N9 is single Core, Lumia 800 also single core, see how smooth is these 2 phone. So, the processor isn't really important.
IF it's not stated in the specs, then people wouldn't know, then they will start to really feel the phone performance by experience instead of looking at spec sheet.
One important thing that many people seems to overlook is the RAM.
The N9 have 1GB of RAM, which is very high and it's a good thing.
4. No hardware button, but on the screen can have button. When you play games or using an app, it will still have button, the most common button is the BACK button on the corner. So, no problems with NitDroid, you will still get the buttons.
