Enjoy it. I also have a 2015 15' Retina MBP that I can do these things on. If I thought any other computer was worth what I get on a MBP, I would buy it instantly. Nothing beats Apple support.
Both of my MBPs have different uses.
You have a rMBP, so my argument doesn't apply to you lol. I love the rMBP. I am simply saying the cMBP is not worth the $1000+ price tag in 2015. I would buy two high end Windows 10 laptops for $500 a piece any day.
