Thank you all for your help! I appreciate it a lot. I'm still thinking about it because I don't want to rush into buying something I wouldn't be hundred percent happy with. I guess I'm still trying to figure out what is it that I really want from a bag. It always seems there's that one thing that isn't like you wanted it to be in your dream bag, isn't there? I have the tendency to try to cram half my house inside my bag to the point where my husband starts asking "do you really need all that in there?" and mostly I don't. In my case this means I'm cramming my phone, card wallet, keys, tiny torch light, eyeglasses/sunglasses, comb, makeup&mirror, pen, gloves, a packet of tissues (and sometimes maybe even a water bottle and an umbrella if I can manage) into a small bag and in the end I'll have to start taking out stuff that doesn't fit in.
I will definitely take a look at the larger S model too. I am finding myself thinking whether I want a really stiff bag or do I want the walls to be able to expand with my tendency to over fill my bags...
