Windows can mean anything, of course. For me it means a Surface RT, Pro and Pro 3, all of which I've owned and loved as devices. It occasionally means a Lumia 635, which was a fab phone, and sometimes means hijacking my wife's HP laptop or, more often, a great many screens in a wide range of shops... If I've popped in to a place with many screens to draw on its generally a Windows device I look for first.
