I also ordered this pack.
My very brief impressions:
The magnet is cool concept, but that combined with the pocket on top, makes for an annoying entry way because when full, it is weighed down and flops over constantly.
It also begs the question, why? It doesn't add much function but does add a little weight.
The shoulder pads are really comfortable and the new stay wraps nicely around your back.
I wish the pockets on the waist belt were larger. They are too small for what I want to put in there.
Finally, the sternum strap on mine broke 2 days after receiving it while just filling the pack and trying it on in my living room. It came undone at the threading on the right shoulder strap. I am quite disappointed with that - and alas, the pack is going back to GG.
