i have a monogram 30 and i love it! i have put my stam away after using it everyday for fall, and right now, im really just enjoying the 30. the 25, for me, was too small and the 30 is perfect for college for me. i can fit my lunch in it, a large evian water bottle, my i-pod video, wallet, sketchbook, makeup bag and lots of other crap i carry around all of the time. it's nice too, because i live in southern california, and the weather in the evening has been chilly so i can bring a sweater too, and fold it up if im not wearing it and stuff it in my bag. now, this may make it seem like its huge, but it's very deceiving. it doesn't look like it should be able to hold all of that...but i guess its like one of those clown cars, and how all the clowns keep coming out...
