I don't get why so many people have to be so hard core one sided.

I have a Galaxy Nexus, Nokia N9 & Lumia 800.

Which do I prefer? All of them depending on what I will do for the moment.

For surfing the Nexus because of its bigger screen and its extremely smooth and fast surfing in Jelly Bean. It's lightyears (slightly overdone) faster than the N9 when it comes to surfing. I hate surfing on the N9 compared to both Lumia and Nexus. Android is also extremely open and can be more tweaked that MeeGo. Also a lot easier to tweak without risking a brick. The community/developer support is nothing short of amazing.

The Lumia is excellent when it comes to navigation. The GPS always locks in 3-5 seconds and Nokia Drive just works very good on it. Socially it is a very good phone too. Some smart solutions that makes sharing easier.

For multitasking N9 for sure. Can't be beaten. For fun factor it can't be beaten either. The camera is lightyears better also. But the N9 feels slow and unresponsive in comparison (opening apps mainly, not to multitasking with of course) with both Lumia 800 and Nexus. Jelly Bean on the Nexus is fantastic. So smooth and pretty fast.

Windows Phone I prefer when I want style and a modern OS to look at with uniformity across the system. It's also even smoother than Jelly Bean and very fast and quick but also limited as we all know. Specilly multitasking.

For audio I much prefer the N9 as it has a very good sound chip that beats the hell out of the Nexus when it comes to audio through the 3,5mm jack. Excellent quality in my Audio-Technica M50 headphones.

Bottom line. The N9 is a fantastic phone but starting to get behind. Really. People need to be more open minded and see the advantages of each system instead of just bashing them because of personal grudges about a system and whatnot.
