Laptops, notebooks etc in theory allow you to roam with total freedom, indoors and out, to find the ideal environment for writing.
There are, however, many disadvantages to the out-of-doors.
Insects, people, sun, rain, prickly grass to name but a few.
The disadvantages can be overcome and most of the advantages achieved by sitting next to an open window.
Provided, of course, that the window gives onto congenial scenery.
