After a few months without an iPad I snagged the 128GB 10.2 for $329 yesterday. I've tried the iPad Mini too, and I feel like if you own an iPhone 11/XR, Max, or Plus model phone, the screen size of the Mini feels redundant. Yes you get a little more real estate, but I'd still prefer to, for example, watch a movie on my iPhone 11 because the speakers are better. Really, pretty much anything I can do on an iPad Mini I could do comfortably on my iPhone.
I've always had flagship iPads, so I won't keep it if it doesn't give me the performance I've come to expect from Apple's products. The only downgrade I'm noticing right now is TouchID being a little slower to unlock. Otherwise everything's running great, the display is beautiful, and I think the stereo speakers sound better than the Mini's.
