For the most part I like it. I just wish the map area was a little bigger.
What do you think?
Speaking only about the look and not the (dis)function here goes...
I primarily use an iPad, in landscape mode, to view the site so my comments are based on that.
Map: Not only does it need to be bigger it should be closer to a 1:1 aspect ratio. On the iPad it only fills about 2/3 of the box it's in. Very wide, not very tall and not very usable.
Graphics for current conditions, temp, wind, pressure, etc.: These take up a LOT of space on the page while providing very little information. I preferred the old look.
Summary (high, low, average): This appears to be unchanged and looks fine.
Graphs: I much preferred the old graphs that showed 24 hours and you could watch the various lines move across the graph during the day.
Overall I'm not a fan of the new look. I'd go back in a heartbeat if I could.
