Some of my impressions so far:
- The keyboard is nice. Not perfect, but tactile enough.
- It's hard to go back to Gingerbread after ICS. It's especially tough to go back to Motorola's customizations of Android.
- I like the design of the Droid 3 better. And apart from the new keyboard and the addition of LTE, this doesn't seem like much of an improvement.
- LTE performance has been good, getting 15 Mbps down and 12 Mbps up.
