Why is it considered weird to use an iPod nowadays?

I have an iPod Touch 5th Generation that I use for music, and the internet. I got it in 2013 but it still works very good for music, I have a lot of songs on it and people make fun of me for using that and tell me to get an iPhone and stuff but to be honest I don't want to waste money on an iPhone, my iPod Touch works fine, I'm using it right now to post this question. Why do people think it's weird to use that?

If I get a Mac, do I need an iPhone?

I hate iPhones so much. Have only had two and they were the worst phones I've ever owned. I have a Galaxy S9+ and it is the best phone I've ever had.

I'm thinking of getting a Mac because my PC always gets viruses. If I get a Mac, do I need an iPhone?

Should I buy the Series 4 Apple Watch, or just wait for the Series 5?

I heard the Series 5 may be released around September 2019 but that may be wrong. What I really wanted to ask is this. Do I need to have cellular on my Apple Watch to be able to pair it with my iPhone? It's like $100 more and I just wanna be sure with that amount of money.
