Hang on what's a 11" pro going to do for me that I can't do on a 9th gen iPad?
$1199AUD v $479. $720 diff
Only you can answer that based on your usage and preferences.
At least for me, the Pro 11” doesn’t constantly reload Safari tabs and apps so it offers smoother performance. It has higher storage capacity for storing part of my media collection on-device. USB-C also makes connecting accessories/peripherals a lot more convenient. Camera is better for scanning. Laminated display feels a bit easier on my eyes. There’s also ProMotion, Pencil 2 and quad speakers but I don’t really care about those.
It’s kinda like flying business class vs economy. Both will get you to the same destination. Business class is just more comfortable (better service and amenities).
