I’ll admit, even though I love my iPhone 4 very much, I DID consider switching to the iPhone 4S just because I have an unhealthy addiction to having the most updated, fresh version of every piece of technology I own. I decided to research the differences; and thank god I did. The changes are pretty minimal, besides Siri (a voice command assistant), who basically acts like your personal secretary. Sounds cool, but when it comes down to it, I think I’m capable of figuring out if i need an umbrella or where the closest sushi restaurant is.
I wrote an article with a more in-depth analysis that you can read, here.
