All over the internet you'll see comments: Which one should I get? Is the iPhone 6 plus too big? Well, today I got an iPhone 6 and determined that it's the perfect size smartphone for almost any hands. My wife's hands are quite small, and she could use it, and my hands are decently large (I have unusually long fingers) and I can easily reach across the screen.
Originally, I was sold on the Plus (I'm not unsold on it), but due to technical difficulties, I couldn't get one. My only choice was the 128 GB White iPhone 6. (I fully welcome the huge hardrive after having to delete half of what was on my iPhone 5 to upgrade to iOS 8) After holding the Plus, I don't think it's as absurdly huge as it sounds, yet I'm still iffy on carrying it comfortably in my pocket.
If you're looking for the safe bet, the one that you will not regret no matter what, get the iPhone 6. It will not feel too small under any circumstance, and it won't feel too large. It's a perfect, comfortable size for web browsing and whatever else you do. I have even been reading my Kindle Books on it, and it's pretty nice.
Camera-wise, I'm hugely against the specs argument with cameras of any kind, but there is a pretty massive difference between the camera quality of my iPhone 5 and my new iPhone 6. The focusing is insanely fast, which is the biggest issue I had with the 5. Photos are just sharper, and the Slo-Mo cam opens up a world of creative video ideas. If you want a great camera, you won't be disappointed. It may not be a huge jump from the 5S camera, but coming from a 4 or 5, you'll instantly notice the difference.
iOS 8 was pretty bad on my iPhone 5 (I would avoid upgrading if you can for now), and I had to charge my phone 3 times yesterday. On the iPhone 6, it's still a little buggy, but not nearly as bad. The battery has been pretty good, but after having the terrible battery life of the iPhone 5, any boost in battery life is welcome. The fingerprint sensor has been a game changer with password input. It's super responsive and saves tons of time.
If you're coming from a 5S, I don't know if it would be worth it to upgrade, since the only real difference is the bigger screen. If you're coming from a 4, 4S, or 5, (or earlier) this is a pretty big upgrade. It's a great phone so far, and I'm pretty excited since it's my first iPhone I got on launch day. I'll be doing a lot with the camera, so stay tuned!
