Does the Cordura erode your clothing?
I'm oh so close to ordering a Smart Alec to protect my 15" Powerbook G4. But here's my fear: my current bag (an aged Eagle Creek backpack with a generic laptop sleeve inside) is made out of such rugged Cordura fabric that it tends to destroy any fine-textured clothing you wear it over.
It's fine when you're wearing a jacket (which in San Francisco is a good portion of always), but I've had it really do some damage to a fancy raincoat and some nice sweaters.
Do I need to worry about this with the Smart Alec?
