Okay, so I've been reading around and I think I've answered my own question.
Here's my findings for anyone else who cares.
So like probably a ton of other Apple fanatics, we've been told that this sapphire glass is the best thing since sliced bread, and that's what we want on our phones. Right? I think so? Okay, well not exactly.
Sapphire glass is extremely scratch resistant, but not the best when it comes to drops.
That's why so many watch manufactures use sapphire glass because you don't generally drop watches.
I'm also assuming that's why Apple decided to use this glass for 2 of their 3 watches. Makes sense now.
Ok now why are they calling it ion strengthened glass? Well, it's rumored that Apple is planning on switching from the gorilla glass that they currently use for their iPhone screens to sapphire glass. Rumored. So it's not some new type of special glass, ion strengthening is the process that's used to create gorilla glass. It's still the same glass, but they're giving it a more generic name to distance themselves from Corning that makes gorilla glass. Supposedly.
While people, like myself, may be "outraged" that Apple didn't switch to sapphire glass, now that I fully understand the situation I'm content with the gorilla glass on the new iPhone 6 and 6 plus.... for now.
