I picked up the new Windows Phone over the weekend. It's been a long time coming and it's even better than I expected (and I'm not saying that because I work for Microsoft). The UI is responsive and very well thought out. The AMOLED screen is really nice with very vivid colors. So far I've loaded Netflix, OpenTable and the Samsung Now apps. I love the tiles and hub concept, it makes for a very integrated experience.
About the only downside is that it can be easy to hit the back or search buttons and so kill what ever app you're currently running. The other thing is I'm going to have to find some sort of stick-on backing to give the surface some more grip as it's very smooth and I'm worried it will slip out my hands.
As I discover new and interesting tips about using the phone I will post them here.
