I'm upgrading from my trusty mum rucksack (since my kids are in their 20's now) would ideally like something big enough for iPad, kindle, passports etc and maybe some duty free, like the idea of the pocket/strap to slot over suitcase handle but not sure if it's that useful irl. I like the look of the nordace bags (online at least), Mia TUI are too plasticky looking. Pretty flexible budget-wise within reason (doesn't need to be designer label) TIA
