The news/weather widget is frequently off center and at night when it's docked I get Celcius.... other than that it works fine.
I use the APK for the Droid New Dock... The News/Weather.. and I don't recall what else but I am only running 3 screens which is limiting.
In portrait mode, the news/weather widget is always centered. In the landscape mode, it doesn't stretch across the whole screen, but I didn't expect it would. As for the Celsius issue, its not an issue to me because when it's in the dock, I'm sleeping, trying to sleep, or just waking up. That's a non issue to me and was noted almost as soon as the .apk came out. What I love about the News/Weather app is the fact you can have it get headlines like for me "Android", "Pittsburgh" (to catch up on what's going on where I just moved from, "Pittsburgh Steelers", "Nascar" "NHL Hockey". And, I like that the stories get updated very frequently.
