As soon as I overcame my prejudice against American coffee franchises (right now I’m in a “Spinelli’s”) I found lots of places where it’s normal to sit for hours in front of a laptop.
Indeed, the only hard part is finding somewhere to plug in — lots of people here have these 1-kilo subnotebooks which seem to last all day on a single charge.
This place has the rare feature of having electrical outlets outdoors, plus a canopy that keeps my laptop dry in all but the fiercest rainstorms. And it’s next to a train station, so there’s an endless parade of people to look at while I’m waiting for compiles.
