I've been using ROS for some 8+ years now, for university projects, competitions like RoboCup@Home and for work on robots operating in the wild, on water, land and among people in malls etc. I've seen many RoboCup teams convert from their custom stuff to ROS because it allows to profit for so much other great work. In my own team, we replaced most custom stuff implemented in the early days of ROS and with ROS with the now de-facto standard ROS stuff for the same task so we can focus more on the stuff that made us win the competition this year :-)
