It is being used in the Maemo on Nokia Internet Tablets, the Neo 1973 smartphone based on Openmoko, the Vernier LabQuest handheld data acquisition device for science education, as well as on the XO-1 laptop of the One Laptop Per Child Project.
It has been replaced on later OLPC software builds by Metacity.
