That 4 year life span is a stretch. I see folk barely get 2 today. The battery times on the iphone are well noted so you can see if that fits your wants. Here I went with a simple (?) android phone from a monthly deal at 35 a month so I'm not that attached to it. No big investment. It does come with the latest Jelly Bean which isn't that important as even the old OS did what it needed to.
I'm getting a new phone to replace my HTC Inspire (contract with AT&T is up, screen's cracked, and for some reason it isn't updating the software to ice cream sandwich or whatever it is anyway). I have a late 2008 macbook that is still running OS 10.5 (before snow lion), which hopefully get updated to the current operating version soon. Now, I'm still up in the air a bit about whether to commit to owning an iPhone or stay with an Android operating system. After all the reviews I've read, and comparing phone models (iPhone vs Samsung Galaxy S III), it seems that they're at the same level. The Galaxy has a bigger screen, a little longer battery life, and stronger processing power, while the iPhone 5 will talk with my mac well (I never figured out how to get double twist to work, which is bad on my part, and I would have to learn how to use it if I got another android), and I do like the ease of the operating system system when I've had to work with others' iPhones.
I merely dabble in electronics knowledge. I just would like a phone that is a good phone (obviously), decent battery life (charge it every day and a half, if that's possible with a smart phone), good camera when I need it, and can record my workouts while playing music. I could care less about 4G because I use my home or work WiFi as much as I can.
There might be a free with contract phone that does all these things, but planned obsolescence happens and I don't mind paying to get a phone that won't be 4 years old two years from now.
Long post, but do y'all have any suggestions? Is there any reason why I should get one over the other?
