I've got a Peak Design Everyday Tote, but the first generation. It simply is functional and really nicely looking ... which, I can't tell abou their recent generation of packs - so dull and boring design wise, while I believe still perfectly functional :-(
As for the Nomatic - I have first seen it with one manager travelling across the Europe. Found it a cool modular system. I was thinking about getting something from Manfrotto Manhattan Mover, which received a Red Dot Award, but might consider Nomatic too.
The Manfrotto Manhattan camera and laptop Mover 50 backpack is perfect for city commuters and people who are always on the move with their photography kit. The Manfrotto Manhattan bags are designed to be carried from home to work or anywhere while you travel, if that maybe walking or cycling...
We will see
