Rental seems to be about corporate laptops. Companies just want things to work at a predictable cost. They are already replacing laptops after 5 years even if they work. They are already replacing a few laptops that break in less than that 5 years. In short they are already renting the laptops, they are just paying the price upfront and then using accounting to balance it out. Rental just moves the accounting, but otherwise nothing changes.

For consumers who don't replace their laptops on a schedule it makes less sense.
