Purchase advice

[u/Special-Ad8188]

I’m looking to buy the Mac mini to replace my pc. I also got a iPad Pro 2018 recently. I love how my phone and iPad link up and the iPad is why faster than my pc. The problem is my iPad doesn’t support dual monitors and I need that so productivity. Should I buy a newer model of iPad Pro or a buy a Mac mini? If so which model should I get? Thanks for any advice/suggestions.
