You can always try selling it yourself, whether it’s a private party sale or contacting Gazelle or Sell Your Mac. If you have a reasonably recent machine that has some life left in it, you may be able to trade that machine in toward a new machine. Once you do that, you have the same options as handhelds: Trade-In, Donate, or Recycle. Just like with mobile/handheld devices, the first move is to be certain there isn’t a machine in your current circle that needs upgrading, be it your parents or children or other people who maybe could stand a slightly newer machine. Now that it's time to get them out of the house, you have a few options. That computer you wanted to fix someday, or the PC you switched from but kept around just in case. After getting rid of cables and mobile devices, now we need to talk about the biggest of the bunch: old Macs and PCs.
