I found the Entourage color surcharge a little incomprehensible, too, but when I went to buy a sleeve for it at a local store, believe it or not, the blue one was $9.95; the red one $14.95; and the purple one $19.95 -- all the same sleeve design. Maybe it's a new marketing trend -- or, maybe China has a surplus of blue dye Needless to say, I now have an EE with a color coordinated sleeve...
