Here's what I've learned - Apple products, like ALL products are unreliable. I have the iPad Air3 and am very pleased. However, the more Apple moves to wireless solutions, the more it fails. I have had very, very bad experiences with such on my iPhone. For example, when my iPhone syncs with iTunes on the computer wirelessly throgh Wi-Fi, half the time it butchers the podcasts I've downloaded, by only downloading half of each podcast which is extremely frustrating if you are listening to a podcast while jogging and suddenly your podcast quits and starts over again in the middle.
The solution: use a cable to hook up the iPhone to the computer. Reality: Wi-Fi syncing is garbage (for me). Wireless FAIL!
Next - I have bluetooth earbuds (not Apple) - those worked fine for about a month, then randomly quit working. Nothing I did brought them back. So I switched to wired earphones (Apple ones). THANK GOD the iPhone 6S (which I have) has a headphone jack. So, reality: Bluetooth connectivity is garbage (for me). Wireless FAIL!
Next - external keyboard (not Apple) - same FAIL story as with earbuds - keyboard worked for awhile, then stopped. THANK GOD I have an Apple ASK - even if it doesn't do portrait orientation which is what I used the bluetooth for. So, reality: Bluetooth connectivity is garbage (for me). Wireless FAIL!
And so on. Seemingly we're making progress, getting rid of wires, but as we all know, it's just another vector for failure to occur (recently my bluethooth Apple Magic Keyboard started failing to connect with my iMac).
The fact is, as these things get increasingly complex, they also increasingly fail. Which is why I like to have options, such as wired solutions, headphone jacks and so on. The more Appple removes such options, the more you're left up the creek with no paddle when the *inevitable* failure occurs.
Which is why I never rely exclusively on iCloud or cloud services, instead like to have my files also kept locally - I've had cloud failures before, where syncing failed or updates didn't occur when I was counting on them. That's a big reason why I bought the 256GB version of the Air3, because I simply will not rely on iCloud as it will INEVITABLY fail at some point. Yet, more and more Apple is pushing iCloud only apps and solutions.
Apple - and everyone else - is moving more and more toward unreliability, and I'm trying to fight it as much as I can.
I find the Air3 more reliable than the iPad Pros in various configurations, what with their screen problems and various other nonsense for which I refuse to pay a premium.
FOCUS ON RELIABILITY PLEASE, APPLE!!!!
