Is there any difference in practice between:
1. iPad (or any other tablet) on rc with wifi and a hot spotting (tethering) mobile phone.
2. Tablet with built-in cellular with its own sim (then the phone is not used at all).
I have been eying the iPad Pro 10.5 to pair it up with my Phantom, but I don't know what to think about that cellular aspect. It seems like the cellular "extra" is ridiculously expensive for what you get (especially as tethering from the phone is so easy and reliable nowadays). But I don't quite get how it all works together with the drone.
I understand also that it's one more device and one more step to get flying, but other than that?
And what do you think about the storage space regarding the iPad. 128 or 256 seems like the way to go, but is huge inbuilt storage unnecessary somehow? I'm not used to iOS stuff, so probably I'm a little bit too paranoid about what you can and can't do on it...
