Hi everyone. Am new to the forum, and loving all the useful info and purse-lust here. I need help! I'm looking for a classic, very sturdy, large everyday bag. Big enough to carry my 14-inch Powerbook, but not too bulky. Had a gorgeous Kenneth Cole NY tote, but my laptop was too heavy for the thin straps, and eventually they broke!!! Have been lusting after the classic Marc Jacobs Stella tote and the new MJ Calfskin Tote, but am open to suggestions. Main concern is strength. Thanks for your help!
