First, you really shouldn't let your friends tell you what to buy or not buy. Advise yes, but nothing more.
Personally, there's a lot about the Apple ecosystem I just don't like. I have no doubt whatsoever that their products are probably great and work together well. But their pricing and the way they treat users when it comes to repairs are the main problems I have with them.
I think it's just better to use what works best for you.
