First off, a desktop would have more bang for the buck, especially when it comes to heavy work as gaming or editing. However it looks like you're in need of portability.
Secondly, I'd advise against buying Lenovo laptops which you can figure out yourself by googling "Lenovo Scandal". Essentially, Lenovo laptops greatly compromise your security and privacy for their own gain. Then it has been repeated after they said to end it. They're sadly not trustworthy. Don't support such a scummy company.
Bullocks. That's a blind mac glorification. Don't listen to that. Consider your needs of portability, performance and budget as well as considering what software you want to use. Mac doesn't have magical hardware: The reason for a mac should be rooted in its nifty os or the need to use osx-specific software. It also flows well with the Adobe programs.
