I really loved the nautical blue and was really disappointed that they didn't carry it over to the 5th gen. I do like the shoreline blue, and I'm sure it will be easier to keep clean. It really does look grey in direct sunlight though, kind of funny because I bought it during a cloudy week- I had looked at it 3 or 4 times during the week and every day it was cloudy
I am just glad it didn't look like the brochure pics, they made it look almost aqua blue...
