This is my green purse and it is nearly perfect. It holds my sidekick in one pouch, (you can see the case for it), and my moleskine and pens in the other (which you can't see as I'm using them to draw). It's the perfect depth to hold my wallet, some watercolors, an ipod and even a decent sized hardback (I always carry a book with me, it's a sickness really). There's a flap in the back that holds my datebook. The strap is serious enough that I can attach my keys and sigg bottle full of water to it without a problem. I love this bag.
