Maybe its just me, but I have never wanted to have a drive sticking out of my iPad. Thats like wanting Apple to add a CD slot to the iPod back in the day.
That's OK. You don't have to use this feature.
For me, I think this was the key improvement of the day.
Now a base 64G iPad will be expandable with cheap USB memory you can transfer from Mac to PC to iPad. yeah it's sneaker-net. I get the 90s reference. But since inbuilt memory was still such a premium very few could afford the top end device.
Going on holidays now won't mean a pre-trip load decision. Take
all your files, your videos and music with you. Possibly you wont even need to take you laptop anymore. I've never taken my laptop out of the bag during a flight. For many business travellers they wont have to either.
Will plugging a phone into an iPad let you access the files there? I'm guessing yes. Hope so anyway.
I'm using my phone more for photos and video too. Rarely use the camera I also lug around in the bag since AirDrop works well and is easy to share the photos you want with other iPhone users. Can you use a hub and plug in multiple drives? Would be nice to move files around on external devices without needing to copy to iPad and then off again to a different drive.
The whole system is really hanging together well. The improved Files app is like icing on the cake!
It's taken Apple a LOOOOONG time to acknowledge the memory/price issue.
Surface tablets were more productive and flexible because you could expand their memory.
This levels the playing field again.
