I'm a long time Android user (and previously used an iPhone as well), but I decided to take the deliciously cyan poly-carbonate plunge with the Lumia 900. This is my first time using WP7, so it is safe to say I avoided a lot of the issues the platform had before v7.5. I was always envious of the new, vector graphics-based interface of WP7... but felt fairly content with Android (especially ICS on my GSM Galaxy Nexus).

So far, I am pleasantly surprised with the Lumia 900. I kept my expectations fairly medium, but for a device that I paid $0 for ($99 intro price and $100 off for switching from another carrier), this is pretty great.

I gave the design a 10 because I feel this is one of, if not the best designed devices out there. I cant stop picking up and flipping it around in my hand, and the cyan color is just brilliant.

The display, while decent, is nothing to phone home about (pun intended). It seems to have fairly nice black levels and decent colors, but the resolution is obviously a bit of a hold back at this screen size.

The camera appears to take fairly good pictures, and I'm pretty happy with the interface and the two-stage camera button.

The biggest hit, of course, is the ecosystem score. I gave it a 6 on the grounds that it had a fair number of the apps I needed (Weather, Kindle, Spotify, Facebook) but fell short on a few others that I enjoy on my Galaxy Nexus (Audible, Instagram (JUST GOT IT TOO, BAH), DI.fm and a couple widgets that I can probably do without). It sounds like MSFT is dumping millions into a few of the big gaps, and I hope they continue this strategy. If they can sacrifice some of their coffers in order to make this a legitimate app platform, they will really have won my heart... they already have with the design and the UI.
