Well, I just ran 2.0 on the interstate for 300 miles. The new features are quite cool, especially the map rotation. But, it's a big drop in stability versus 1.4 (certaintly understandable ). I had more than a dozen crashes over the whole trip (which is a bit of a pain at 80mph ), now, since I was cruising down the interstate, I couldn't really say for sure but I think it may have failed on map downloads. I pre-cached along the route before I left this morning, but I may have gone out of the cached zoomed levels and I don't think it liked trying to fetch over the EDGE connection on my phone.
