My 1st smart phone was an iPhone 4S and I made it last nearly 4 years. I upgraded to a 6S when it came out and it feels like it still has plenty of life in it, definitely enough to make it last another 2 years no problem. However, not too long ago, I had to switch the computer I was plugging my phone into which caused a major flaw of iPhones and iTunes to be exposed. I was able to backup the important stuff but there was no way around it, all my music and media was going to be erased. I never want to deal with that again and I don't play phone games so I'm thinking, I'm definitely going to jump ship to a Galaxy S in the next round.
Have you jumped ship before? Phones aren't as a big deal as they were a few years ago but we still use them everyday and they're quite a hefty investment so it'd still be good to get some perspective. Is the grass really greener on the other side?
