Points about rucksack vs tote taken on board. I tend to swap my bags around a lot. Sometimes when there's a lot of working I'll be doing rucksack and small cross body handbag. (Mulberry Anthony is fab for this). The tote will be for days when I'm only carrying all the gubbins short distance and need a handbag for the rest of the day. Usual contents are laptop, electronic notebook, headphones, purse. No paper thanks to paperless office and I tend to leave my water bottle and coffee cup at the office (otherwise I forget it).
I've a free evening in London on Thursday, might head to Liberty and John Lewis to look at the bags in real life.
have just realised the Demellier one is suede, which is making me wobble slightly, but it's beautiful
