To me, the hard cases add too much weight. I have a 13", but the case I bought is available in 15" and 17" also. It is the Incase Protective Sleeve Deluxe and I really like it so far. It seemed more padded and protective than the incase neoprene sleeves plus it has a small outside pocked plus the lower corner where the charger plugs in has zipper access to the ports in that area of the computer. I am not sure if it is safe to carry the MagSafe plug in the pocket as I would be afraid of the possibility of it denting the case, but I am going to do some more research on that before I eliminate that possibility. There were several colors in the store, however, and I was specifically looking for a faux fur lining to avoid scratching my case. The black and brown ones had more of a quilted lining while the white/gray one I got has the fur. It also has kind of a pleather feel to it, just feels more protective than anything else they had in a sleeve at the Apple Store, Best Buy, or Sharon Luggage, the three stores where I looked before deciding on this one. The Apple Store also had the Hurley sleeves that felt nice but they were neoprene like the cheaper Incase ones and I liked this deluxe version much better. It's a tight fit, which is what I wanted, and it looks great!
