I have a perfect couple for my MBP 17:
an axio softbag which is really cool as it is designed vertical and not too baggy, but still has place for all the stuff you need to carry around with you: adapter, power plug, mouse, mobile, book, cables etc.:

perfectly snugging into the axio bag is this hardsleeve from booq:

other hardsleeves I have experienced are much too big in size, this one is very close to the shape of the mbp itself without adding inches to the sides.
was was important to me: beeing able to open the zippers fully around, not only half way like many softsleeves do.
(there is also a hardsleeve from axio, but I think it looks ugly - you can see it in the pictures on the linked site above - but I dont doubt if it fits as a 17 "in the bag. I think they combine this bag with a (big!) 15" hardsleeve, not a 17". But with the booq sleeve, you can put a 17" with double protection in.
so I can combine these two in every way I want: sometimes I just take the hardsleeve, sometimes only the bag (but no, I very rarely do that) mostly I take the combination of both: it fits so well it seems like it is made for each other. I can easily slide the mbp into and out of the two without any hassle, as they stick together quite well.
this combination is good looking, really protective but still light and not too bulky. Oh, and the price was quite nice, too. Both together for much less than what I'd pay for a crumpler bag or else.
