I was thinking of buying that mini vacuum on my wishlist and also that spray stuff to clean my computer the next time I open it. I was afraid that the mini vacuum (http://store2.yimg.com/I/lmcomp_1784_3929730) would have minute amounts of static build up, so I was thinking of buying the spray stuff separately for getting rid of the dust inside my computer (http://store.yahoo.com/lmcomp/80009.html). Does this seem reasonable?
