I have a Swiss Gear backpack for my MBP. Similar to the one you listed. It is KINDA big... but you got to take into account for all the pockets it has. Sometimes I forget where I put things because of it. I use to carry my MBP, Binder, 2 Textbooks, My Taekwondo Uniform, Change of Clothes, my iPhone, pencils, pens, keys, and everything else and it held up GREAT. It was a heavy backpack for me indeed because of all the stuff. This recent semester that just ended.... I didn't use my Swiss Gear backpack since my classes didnt need me to have my laptop with me... But this coming fall.... Looks like I'll be using it very much. Its been over a year since I've had it and it's like new 
Good Luck on whatever you choose.
