In my opionion, I think CO2 cartidges have dubious value. You can get small bicycle pumps that are lightweight, and probably amounts to less weight than carrying several CO2 cartidges and a CO2 pump.
Also, I'm not sure what kind of bike you're riding, but dirt bikes don't require much air, so pumping the tire to, say, 15 PSI really isn't much work.
Lastly, there's always a possibility that you'll run out of CO2 if you get multiple flats, and you'll have to pump the tire anwyays - becase of that, I woulnd't even consider getting a CO2 dispenser that doesn't double as a pump.
If I was racing, I might feel that the very small amount of time I'd save was worth it, but definitely not for casual riding. For travelling, it's just more loose bits to carry around, you have to worry about replacing them once you've used them (I always forget to) and I just don't find them to be much more convenient than a pump.
