In reply to TheDrunkenBakers:
Not much use to you, more a nod to Pod rucksacks and simple, robust designs. I've been using the same 25l Pod Teardrop for 18 years for work. It's black, even blacker where I've stained it with ink, but is not even starting to wear out. It has one pocket and one main compartment and that's it. I put a 15" laptop in it, in a padded cover, and sometimes it is handy to just take that cover and leave the rucksack at home.
If I were buying one now, I'd get one of those Fjallravens described above. For my wife though, I've just bought a 24l Osprey Sirrus, for day walks. It has all sorts of compartments and pockets and she will love it.
