Cinched up, the Brain Bag looks really slim, it is a workhorse and with the addition of a Brain Cell will make carry your heavy windows machine easy.
I carried 2 iBooks in it which are fairly heavy, decade old, notebooks.
To protect it when you put it down you could try the penguin egg carry, place the bag on top of feet, squeezing the shoulder straps between calves.
This way both hands are free to hold on, you can still shuffle (penguin style) and good luck for any pickpocket to try dislodging it from your grip.
When it is time to leave, grab the top handle get out, put the Brain Bag back on and you are on your way.
