I have to plug my BOBLBEE hardshell pack which I've had for about 5 years now and which shows no signs of quitting. The hardshell has been great for protecting my laptop from a number of falls which I'm sure would have been deadly in another pack, it doesn't look like a "business" case/pack and it has a number of hardpoints to attach accessories like a cargo bridge or extra bags onto.
I've been able to fit it neatly either into a 777 C-class overhead bin and also under the seat in front of me on an RJ, so it really does go everywhere with me.

Axio makes some hardshell packs that have slightly more "professional" lines at the cost of holding less.
