Time for people to realize that too much screen time actually hurts our well-being.  I work in IT so I already sit at a computer for a long time every day, and I try to limit my screen time as much as possible outside of work.  When I go to a coffee shop, I usually just bring a book and sit there for no more than 30 minutes, which is enough to get me relaxed and refreshed :)  

I also feel that it's not fair for me to just buy a $2 coffee and sit there for hours using their free Wi-Fi - it's got to hurt their business.  I'm all for getting rid of Wi-Fi in coffee shops and they can offer nice music and books/magazines instead.
