I have a desktop PC at home in a home office. My wife is right near me. I think this is probably a problem because I also play games on it so the room sends very mixed messages to my brain. I help with a small business so have to use my PC for that. With my day job I have a laptop provided and do move around the house to get a mental disconnect and help me focus on some tasks. The problem is it's not a great device for stuff like in-depth research, I really want a big screen for that, so usually have to use the PC and get distracted.
