I got the incasde hard case. And then I got a Brenthaven II sleeve (with a pull out handle). This works great for back and forth trips to work. For an airplane trip I use my Targus backpack...which is great for carrying many other items on board!
I always treat a new laptop to ShaggyMac Screen Protector & Polishing Microfiber. Helps keep my MBP mint and protects the screen from scratches & scuffs.
