I'm still using a couple of ancient 15.6" Windows laptops (the cool kids all laugh at me) because they have 1920x1080 and 1920x1200 displays -- and I'm in my fifties, finding that my arms get shorter and shorter every year (that is, creeping presbyopia -- combined with myopia -- means that I need different glasses for everything now). Apart from text-based activity (development and such), I do a considerable amount of image manipulation using Photoshop and plugins. Current-model affordable machines tend to have resolutions that are far too small for my day-to-day use, making me choose between UI elements and what I'm working on. 1600x900 is far too restrictive (and yes, I own a machine with that resolution), and I'd really like the option of taking my work with me without carting around a separate monitor (the reason I use laptops in the first place).
