Amazon brought this to my attention:

Metro Vacuum ED500 DataVa 500-Watt, .75 HP Electric Duster (actually a
blower).

I know you're supposed to blow the dust off of equiptment and out of motors
every once in a while. Do you folks who do this use dedicated compressors?
This seems like it could perform dual duty (In the computer room and the
workshop), is exceptionally portable and doesn't take up as much space.
What do you think?
