I'm a law student and thinking about ditching my MacBook for my iPad to take reading notes and class notes. I also work full-time at a law firm. I'm looking for a bag (messenger or backpack) to hold the iPad, keyboard, cables, accessories and a 2-3 inch textbook. Something functional and stylish but also professional and not too bulky. I've been looking at STM (look too small to hold a thick book), Incase (love the design and functionality more than I was looking to spend), Case Logic, and Timbuk2. Any other suggestions or input? Much appreciated!! Cheers!
