i,m wondering if anyone has ever used compressed air in a can to clean dust from sensors and lenses, if not, what is the best and easiest way to keep them clean?

Don't use them.
They have liquid propellents and if they land on the sensor, it can cause streaks/marks to appear on your shots.
Use a large hand powered air bulb instead.

do not use compressed air

..

Heck, I use a t-shirt and a vacuum cleaner...I'm pretty brutal with my methods, and even I wouldn't use compressed air.

I would say that it would be a good policy to avoid touching the sensor with anything other than the proper equipment. You can buy sensor cleaning kits.

Cleaning lenses is significantly less hazardous than cleaning sensors. I am not afraid to use a silk tie or a cotton shirt (I use the underside which is less likely to be contaminated with dust).

I recently picked up a lens pen for a few bucks and it's fantastic at cleaning lenses. It doesn't leave any little marks or streaks like a t-shirt usually does.

I just about went insane when I went to Hong Kong and I tried cleaning my lens, but between humidity in the air and sweaty fingers, I could NOT get a streak-free lens on my little S30. I went to a store and they sold me some overpriced bit of cloth which did nothing and I was quite irritated.

A lens pen would have taken care of that in a matter of moments.

Absolutely not, they leave fibers behind. NEVER use them on the sensor, you're in for a world of hurt if you do.
