I just got my white 160/6 from CDW on Friday and no, there was no sleeve. I don't think it would have even fit in the box the way the packing was designed. From the reviews I saw that mentioned and showed the sleeve, a) it didn't look like the sleeve would fit the new model's battery bulge, and b) it didn't look like a decent quality sleeve anyway.
I love this AAO, it is really everything I expected it to be. For carrying & protection there are tons of different portable DVD cases at places like Walmart, and also some decent looking memory foam hard cases with room for the AAO and accessories. But I'll probably get something like Acer used to include with the AAO - that'll probably be about right for tossing in the briefcase, and also get a smaller & lighter briefcase now that I don't have to carry around the old "full size" laptop.
