Pretty excited to be getting my first new phone in 3 years, a new iPhone 6S, this week. (I pre-ordered through AT&T.) I got my first iPhone in June 2008 (iPhone 3G). Then the iPhone 4 in 2010, then the iPhone 5 3 years ago in 2012. So I've never owned any other smartphone. They've been great devices for me. I did have a couple of hardware problems with the 3G - the WiFi transceiver on my original iPhone 3G failed (entire device replaced under warranty), then the replacement eventually quit alerting when texts came through (also replaced under warranty). No problems at all with my iPhone 4 or iPhone 5. Apple also won me over with their superb customer service. The one and only time I've damaged a phone, they replaced it for free at the Apple Store in Germantown, TN., no questions asked, even though I didn't have insurance on the phone (cracked screen from being run over when it dropped off my lap into the parking lot when I got out of my truck and forgot about it). I've also appreciated the durability of the phones - I am an aircraft mechanic by trade, so I'm constantly getting oil, grease, corrosive hydraulic fluid, and fuel on the screen. Still, it works great even after 3 years. My iPhone 4 was the same... If I've had any complaint at all, it has been the limited storage of this iPhone 5 (it is 16GB). But that's my fault for not buying enough storage to begin with (this will be solved with my new iPhone 6S - I went with the 64GB model). So I'm thinking this 6S is going to be the biggest performance jump I've had so-far. Going from the 3G to the 4 was a pretty good jump, and then from the 4 to the 5 was even bigger, especially due to the 4G LTE capability. But they're saying that this new iPhone 6S is gonna be, what...70% faster processor speed than even the iPhone 6? So how much faster than my iPhone 5 will it be?!?! I can't wait to find out, and also to be able to use, not only all the features that will be new to the 6S, but all the features that were introduced on the iPhone 5S and iPhone 6, as well! I have to admit, I am not really super "up to speed" on all the latest tech stuff, although I do appreciate it. I don't even really know all the differences and new features of the post-iPhone 5 phones. It seems that most of you, here, have been upgrading pretty much every year.... So, from the perspective of someone who hasn't upgraded phones in 3 years, since I got my iPhone 5, what do you guys think the biggest differences I'll notice will be? Anyone else here who is going from an iPhone 5 to the new iPhone 6S? P.S. I just received an e-mail from AT&T, as I composed this thread, that my new iPhone 6S has been shipped, via FedEx, and will arrive on my doorstep before 3:00 pm on Friday!
