Laurent Lachal, U.K.-based senior analyst at IT advisory firm Ovum, said inconsistencies across Linux distributions still stand in the way of wider user uptake.
"For one, Linux has two main GUIs (graphical user interfaces), KDE and Gnome. Some see that as choice, but overall it confuses the market," Lachal told ZDNet Asia in a phone interview. He added that each GUI is further tweaked for different distributions, further compounding the disparity.
Different distributions also have different ways of allowing users to perform tasks, such as terminal commands.
Some distributions also try to mimic Windows as closely as possible in order to entice Windows users to migrate, but has often resulted in only "good enough" experience for "basic" enterprise tasks.
