I received my phone yesterday and first impressions are positive as I thought they would be. I used the Trophy quite a bit. The screen is incredible. I thought the G2 had a great screen until I used this one. The operating system is smooth. The camera is much better even with the slight shutter delay. Some of the apps are a joke compared to Android but not a big deal either. I can use mobile sites in many cases. I like the pillow charger that came with it too!
Three improvements I would like to see are better vibration (it is way too weak), the name of the person in text messaging in addition to the phone number and predictive phone numbers when dialing and not using bluetooth. For example, if I type in the first 2 digits in a phone number, it would display all numbers that have those as the first 2 numbers.
Overall my first impressions are positive. Unlike some, I find Windows Phone easy to learn. I do think linking email accounts could be easier and a little more intuitive though. It should be more popular than it is but many will unfortunately believe joke reviews like those on the Verge (Apple fanboys).
