Just got my new pb 12 on friday (this baby is all that I hoped for).
Today went looking for a hard case (wanted more protection than a bag). Bought a Compucase aluminum thinline laptop case at Staples.
This case is perfect, will also definitely fit the 15's. Best of all, the case was only 49.99
If you're in the market for a slick looking hard case (thinline aluminum breifcase style), you gotta check this one out.
