This thing is fabulous! Just picked it up today at the store after pre-ordering it. I can fit my iPhone, wallet, Google Nexus 7 in its case, pocket knife and a writing pad. It can easily fit more, but for illustration purposes this is what I put in it as soon as I got it home. I also got it with the waist strap. I will post up come pictures when I get that set up. Thanks TB Crew, this is the greatest little bag ever!
