I use it a few times a week for about that long, almost exclusively as a virtual display for my MacBook. I bought it mostly because I travel for work, and when I'm stuck in a hotel and want to work I wanted something similar to my big screens at home. It's also nice to be able to kick back and watch big screen movies or TV on travel too. Long usage is fine for me - with the inserts I have my computer glasses prescription so things look good.
