I am about to sell my mini, but was reminded that I'd been wondering what holds more - the mini or the small classic flaps. And silly me was about to sell my mini whilst I had a small classic in the same house without comparing! So I got carried away a bit, but I hope this might help someone who does a search. I did a little comparison of all the 'classic' sizes I have, too (M/l down to WOC). For mini vs small, ultimately, there's pretty much nothing in it. Maybe an extra lipstick could fit into the small, but the double flap really does affect it much more than I expected! I also got all into it and whipped out my four thirds camera so I could use my mobile phone in the contents shots. Then totally forgot to actually do that
