A couple of comments in response to several messages:

Yes, it takes a minute or two to hang the Platypus - and not much longer.  On a travel day, that can be inconvenient, but then if the kit is easily available it's worthwhile.  I carry a filtration water bottle just in case - it's just dip and drink.

I used to pump - minimum 90 strokes per liter, with filter cleaning about every five liters.  That was a royal nuisance, as was anchoring the canoe in the middle of the lake while I pumped.  Got rained on a lot those days.

The Platypus does slow down, but it does not clog except if water bubbles get stuck.  In both cases, the cure is simply backflushing for a few seconds.

I don't care about getting bark in the dirty water bag because it gets dumped out the next time I fill it.

As always, to each his or her own.
