Depends on your eyesight. I find reading text on the TV difficult. So I tend to edit code, read articles on the MBP and browse web sites using the TV. When working from table and chair, I tend not to use the TV. Working from the couch is good, but the cable tends to get in the way to the other occupants. I have tried ChromeCast, but it is too laggy for my taste - so I tend to only use it for YouTube, etc.

I use a 4 port HDMI switcher. The signal quality is OK, but the dinky remote control is a bit of a pain.
