I've been using a Bitolithic sleeve for a week with my new Macbook Pro:
I am very happy with this product for a number of reasons. First, I wanted a thin protective sleeve for placing my laptop into my sling backpack. I didn't want or need anything thick or highly protective - just something to protect against minor scratches. This sleeve is thin but protective enough. Second, the sleeve comes with a zippered bag which is more than large enough to carry almost all of my accessories (and all of them when I'm not over-accessorized). Third, it comes with a screen-protecting cloth.
Personally, I'm a fan of RadTech Notebook Screensavrz and use one of those (the black one with the 'X' logo), but the supplied cloth is perfectly acceptable. It is, as pictured, orange, which isn't a problem for me, as my university colors were blue and orange.
I use it to wrap my spare battery to keep it and things around it scratch-free.
One of my favorite features of this sleeve is the fact that the zipper can almost completely unzip the top from the bottom - they're attached by about an inch at the center of the back. Why do I like that? Two reasons. One, I can leave only the small area by the power port unzipped so I can charge my MBP without any part of it being exposed. I don't need that, but I like it. Second, I can unzip the side as opposed to the front, and slide the MBP in and out that way - very useful when it's in the sling backpack.
Good product - recommended by me.
