I find it very convenient just to be able to have a sip when I want
instead of having to stop, faff around behind me to find a bottle,
then carry on. The only problem I have with them is not knowing how
much water I have left. I've certainly not had a problem with gunk and
so on in them, and I've only ever cleaned mine thoroughly the once
(then again, I never put anything in other than water). IMO they're
far less of a gimmick than, say, GPS.
My Craghoppers rucksack has front "balancing packs" (!) which consist of
two sets of two pouches (zipped inside, open netting outside) and are a
great place to put
a) outside left: water bottle. Takes a litre with no problem
b) outside right: camera for quick photos. (cover when raining!)
c) inside left: light gloves
d) inside right: currently unused
I wouldn't swap my rucksack for any other.
