CO2 cartridges can fail and people use them incorrectly, and if you don't have a pump, you're plum outta luck. Also, what do you do with the spent cartridges--just throw them away? That seems like such a waste somehow.

So even if you use CO2 cartridges, you might still want to have a pump for backup.
Can't disagree with a word you've said. Pumps provided unlimited air and don't fill up the overstressed landfills.
