Input:
I was buying this to replace a bag I have that is similar.  I was a bit wary of the purchase because I liked my old bag so much: it had been with me daily for 11 years. I was also concerned that the outer material would look too cheep to use in a business setting, but it doesn't.  The only flaw I see is that the flap is a bit lightweight.  I think it will blow around a good deal if not clipped (something I never did with my last bag. Also the clips on the backpack straps are hard to get undone and plastic.  As I am not planning on using it as a backpack, this is not a deal-breaker for me, but it would be a consideration for people planning on converting it a lot, or using it as a backpack a lot.
