A lot of people, including young people, throughout Asia don't have computers. A large number of working adults our age (however old you may be) don't touch desktop or laptop computers at all on their day to day. A huge number of people only have phones in their home and only use phones for their work. Plenty of companies also use tablets with specialized apps in places where a western company would use a PC. Finding 20-30 somethings in Asia who are educated and employed who don't know how to use a mouse isn't uncommon. I've encountered it loads of times with new employees in various offices.
