Just picked up my N9 this week. I'm using it as a stop gap till I decide on either WP8 or iPhone5 later in the year.

First impressions are positive, but my biggest problem is that screen! Next to my iPhone 4, websites looks awful. There's a weird discolouration to everything, most noticeable on predominantly white backgrounds. It's greenish tinge. The iPhone looks like a piece of crisp white paper. The N9 makes it look like a yellowed old newspaper! Even before I put the two side by side, I noticed the screen when web browsing wasn't reproducing colours accurately.
