Usability issues? Heck I can't even get the program yet. The downloads are continuing to come up as 'corrupted file etc etc'. Bizarre misleading error message and it tells what? As a base user, I am not doing backflips or 'other' mirrors or install variations. The point is The Program itself, period done. At this point it has AVAILABILITY issues.
argghhh see ya maybe in six months to a year, I hope.
