>>The Mac Mini is an entry level product I see quite lot of people pick up. How is it niche?

It's a stationary computer that requires a standalone monitor, keyboard and mouse/touchpad. People just buy a laptop instead, a dedicated "computer" space at home is increasingly a thing of the past. And especially now if you can get the Neo for very similar money I have no idea why you'd buy the mini if your entire computer use is Facebook and maybe some word editing from time to time.
