I don't often use my phone as a "device" for anything more than variations on messaging apps for different projects and tasks. Despite their best efforts, the browsing experience on a cell phone, even one with a large screen, is incredibly unpleasant for one with poor eyesight.
One bright side to poor vision: my 2HD monitor is effectively a "retina display" because I can't even begin to focus on individual pixels with this thing. *LOL*
