There's never a 'point' buying Apple regardless of light/heavy use. You buy Apple if you think it's the best OS/hardware combo, you don't if you prefer otherwise.
Even light use will benefit from long battery life, nice screens, and quality construction, and a low cost windows machine will not have that. You can get a good windows machine with comparable hardware, but then it's not low cost anymore.
