Jeff,

Thanks and I am aware of the moisture content of compressors.  I had a 
small one at the shop for years and never had an issue with it.  As much 
as I like the portability of the small cans of air, I do not like the 
price.  $6-8 for a can of air?  Depending on where you buy them, they 
can be quite spendy, and when you go through them as fast as I do, it 
adds up quickly. 

Besides, computer cleaning should never be performed with the power on.  
They should always be Shut Down properly, and then unplugged to remove 
all power from the system.   After using a compressor, I always let the 
computers sit for a while so any moisture that does escape from the can 
or compressor can evaporate. 

I recommend cleaning your computer twice a year, following the Daylight 
Savings Time dates.  From the looks of 99% of the computers I used to 
get (and still get) most people never clean their computers - ever.  So 
twice a year is much, much better than nothing at all.  And if you're a 
smoker, no cleaning in the world will get all that black sticky gunk 
out.  You should never smoke near your computer.  That white fluffy 
'dryer lint' dust turns into a brown, sticky, smelly 'tar' that will not 
blow out easily.
