• Regardless of physical dimensions, a fine dot pitch display. My current screen is a 15” normal (non-widescreen) display SXGA+ which has been great. That works out at about 116 DPI or a 0.2177mm dot pitch. It’s well worth whatever it costs extra to get a good built in display. Screen DPI calculator.
  • No shiny / reflective display finishes. Quite simply, a deal breaker. I hate those shiny screens.
  • Built in serial port. USB to Serial converters are such a pain. Having a permanent /dev/ttyS0 makes such a difference.
  • A good keyboard, or at least, one that you could type on all day without causing injury.
  • SD card reader.
  • Reasonably sized hard drive and lots of memory. Probably more important than a grunty processor.
  • Sensibly positioned USB ports and other sockets. Preferably on the back, as frequently used ports on the side can be annoying.
