More like I don't want to move my entire PC to somewhere when i can instead carry a 200 gram can home .
You should do it regularly anyway, to avoid dust buildup, especially on laptop. In laptops, you can eventually get a compressed ball of dust that is too big and dense to get out of the fan assembly without opening it up entirely (which might void your warranty). Regular de-dusting lets you avoid the problem. Every couple of months is fine.
Not to mention, you can flip the can upside down and terrorize people with -40 C stuff in the back of their necks.
