I'm on my 3rd Manhattan bag. The past two just wore out. I washed the gray one so much it lost its color. Must have been at least 10 years old. I love this bag. The new back open pocket. The last two didn't have it. The slightly larger size (I think). I carry my Mac Air or my iPad. Papers. The usual stuff. Bought an accessory bag to had to the strap. Perfect. When you live in Pittsburgh, you notice who else has a Portage bag. Nod. Nod. Wink. Wink.
