iPad mini + iPhone 13 Pro > Galaxy Fold
The above is an excellent overview of the new iPad mini and it covered what the benefits are in the real world.
When Michael talked about the Galaxy Fold and the potential of 2 Apple devices fulfilling what it does this made a lot of sense to me. iPhone 13 Pro (£1,049) + iPad mini (£479) = less than the £1,599 Galaxy Z Fold3 5G.
I have never seen a use case that would suggest that a folding phone makes it worth the extra cost and when I compare it to those 2 devices it seems like a no-brainer to me.
