Hi Audrey! Both the 15/13 Cadet and the 11/iPad Cadet will fit a legal pad, which means that A4 paper should fit nicely too. As for how thick a stack/notebook will fit, it looks like about 1/2 an inch for the smaller Cadet, and maybe as much as an inch or more in the larger Cadet.
Well, I finally took the plunge, I just ordered one! Can't wait :)
I bought the 11" size in cardinal/steel, I hope it arrives soon too :)
BagMonkey...I love your handle ! Looking forward to the report on this...you can tell your wife it was my fault!
I have the smaller Cadet and plan to do a review in the next few days. My initial reaction is....well, you'll have to wait. :)
I have the smaller Cadet, and my 13" MacBook Pro fits in it just fine. It won't fit; however, in a sleeve. I've hauled the thing back and forth to work without any problems. It's padded on the front, back and bottom, just doesn't offer much protection on the sides. I also carry my iPad 2 in the sleeve right next to the MBP, and there's plenty of room and protection for my comfort.
Just ordered one for myself last night - the black/iberian combination for a 15" MacBook Pro with the Absolute Strap - which will match my first Tom Bihn bag, an Aeronaut I purchased back in March. I hope to receive next Thursday, provided the gods of delivery are kind!
