At my old house, in the attached 2 car garage I had my son's old Dell desktop on the bench and the monitor/TV up in the wall cabinet over it. Handy to look up parts, installation/service manuals, etc. I also used to stream Pandora, and ran a cable so I could watch TV.
Here at the new place, the shop is 150 feet away from the house, and the wifi signal doesn't quite reach that far. I've ordered a wifi extender, once it's installed it'll be nice to be able to surf without coming back to the house.
No cable out to the shop yet, but I picked up a TV antenna and a digital/analog converter box and hooked it up to the free big screen TV I picked up CL, it pulls in all the local HD over the air channels just fine. It also has input jacks for audio, so all of my music on the Mp3 player sound nice and loud through the huge speakers in the TV.
Both my kids are in college, whenever one of their electronic devices (laptop, PC, phone, camera, whatever) quits working or they just get a new one, they give me the old one and I can usually get it going well enough for me to use. As a result, I've got a Toshiba laptop, Dell desktop, old iPods, etc to use in the garage/shop for free.
