Most of the week, I carry my laptop in a Brain Cell, 1 L water bottle, lunch, and miscellaneous items (charger, cell phone, keys, wallet, etc.). However once or twice week, I'll usually head straight to the grocery store from school and get groceries for the week (usually including a gallon of milk, maybe 0.5-1 gallons of orange juice, etc. and these go into my backpack to be carried home) I currently have a Swiss Army/Victorinox Sorbonne backpack which is ok for my uses so far, but the middle/secondary compartment isn't nearly as sturdy as the main compartment and my vertical Brain Cell does not fit well at all.
I'm trying to decide between a Brain Bag and a Smart Alec (been saving money for a purchase for a while now). It looks like the Smart Alec might be too small for my uses... but I'm only 5'1" so I'm really hesitating. Any insight or photos of a Brain Bag on a smaller person?
