I meant more that you rarely see them on Freecycle or anywhere, whereas desktop machines are much more common - we don't seem to have these special days for leaving out computers and stuff anyway, you have to takeI have yet to find a laptop of any description out on trash day. I think, though, it has nothing to do with them not being thrown out as much as it has to do with them being small enough to fit into a black plastic garbage bag with the rest of the trash. Thousands of laptops probably get thrown out every day, you just don't see any of them because they are bagged.
to the local tip or arrange a collection instead for anything like that which shouldn't be put out with the ordinary rubbish.
