I carry one of these AS WELL AS a decent mini pump for any journey on my road bike. Its a convenience thing, especially when you're tired/its raining/you're cramping/out with friends and are keeping them waiting. The arguments are all here. If I'm out on anything else, a decent mini-pump will get enough air in.
As for the environmental bit, the cylinders are steel so you can stick them in the recycling in the vague hope that they'll not become Chinese landfill.
Something that I've found for tyres inflated with CO2 is that they will go down over a period of days. If I've used a cartridge, I usually deflate the tyre at home and re-inflate it with a lovely big track pump.
