I have to agree the "canned air" shouldn't be on there. For one thing it's definitely NOT canned air, else it wouldn't be so toxic and explosive.
And besides, there's nothing pretentious about spending a few bucks to clean out $1000+ equipment and increase its life expectancy, and reduce its energy consumption.
My mom was about ready to buy a new laptop because it kept overheating while she was playing Farmville (first world problems?), but after spending a half hour taking it apart and cleaning off the dust that was caked onto the heatsink's intake vent, it runs good as new. I didn't use canned air to do it (just some dry paper towels) but I think the point still stands ;)
