It's time to upgrade both my wife's and my phone. We have Droids right now but she's been asking whether we should move to iPhones. She loves her iPad, but that's the only apple device we've owned.
Key criteria for us are to get the best possible camera, storage isn't that important as we download the photos and videos to our computer often; I put music on the phone to listen to while cycling, she rarely listens to music on hers. I'd like good speakers for use at home. Water proof / resistance is a must - sweat and I put my phone on top of the shower to listen to it (although I can use my current phone for that in the future).
Is the 6+ too big?
Is the 6 worth much more than the 5s?
Is an iPhone that much better than a Galaxy / Droid platforms?
CAMERA: Pretty big improvement with the new 6/6+ over the 5s. I'm a fan.
SPEAKERS: Exterior speaker on iPhones are louder than most, but still would recommend an external speaker or playing via airplay for at home
WATER RESISTANCE: Galaxy S4 (I think?) has a sport model that's most waterproof. However most phones now are pretty water resistant (splashes, a quick dunk). Posted link on this page to the iPhone 6 dying after 53 seconds under water. Lots of vids of it going under for 5-10 seconds without any ill effects. That said, DIRECT (not a light splash or mist) water exposure will void most warranties. Sweating, or in shower out of direct spray shouldn't be an issue with any phone though.
TOO BIG: HIghly subjective. REALLY should visit a store and handle both phones. For my purposes, the 6 is the perfect size as I use my phone on the move more, and value one handed use. Others prefer the phone to function more as a mini tablet and value the increased screen real estate over a little more portability.
6 WORTH IT OVER 5S? I think so. Better/bigger screens, better battery, better camera, faster processor (snappier), mobile payments, improved health sensors...
MUCH BETTER THAN ANDROID: Again, a very personal decision. Both Operating systems are very solid these days. Some tout Android's customizability as a strength over iOS. Others tout the fluidity and security of iOS over Android. I'd use flagship phones on both platforms and go with what works best for you. Be cautious in the stores as they're usually populated by phone dorks with strong opinions one way or the other.
