@stroughtonsmith disagree. A) light computing isn’t just about price. B) You can get an iPad for less than half the cost of a Mac.
For casual computer users an iPad does pretty much everything they need to. My 70 yo father would rather spend £1k on an iPad vs any computer for the same money because of its ’lightness’. There are plenty of people who don’t need the complexity of a Mac, including its hardware complexity.
