@_manZzup_ Depends on the type of trackball. In my case, transition to the MX ergo was pretty natural, it's a thumb-operated trackball and quite close to a normal mouse.
Also tried out Elecom Huge which is finger-operated, was much harder to get used to.
@thameera :/ Doesn't sound that bad for the existing users though. I guess most people choose Antergos or Arch derivatives to bypass some of the time consuming installation steps in Arch.
