Just purchased a 13" Macbook Pro Retina and want a good backpack for everyday commuting and occasional traveling. I will also carry an Ipad Mini, on-ear headphones, glasses, sunglasses, Nintendo 3DS XL (I'm a Luigi fan) and work documents. Based on everything I can find about the Smart Alec, it appears to be the right size for everything. However I just can't pull the trigger because I am so impressed with the Brain Bag styling. I'm concerned that if I use the Brain Bag it will be cavernous and difficult to find equipment quickly. Someone familiar with the bags, please give your opinion as to which would be the best option. Also, would including a Freudian Slip and Verticle Brain Cell make the Brain Bag more managable? Look forward to getting some great insights.
