Hi, My iPhone 5 is slowly showing its age and I kind of want something new. Its 16GB are to small, performance is decreasing, a bigger form factor would be nice and I start to hate entering my pass code 20 times a day. I love the features and overall package of the new 6S, which would cost 850€ here in germany for the 64GB version. Not counting for a decent case, new bike and car mounts. A refurbished 6 with 64GB in almost new condition sometimes appears for 599€ at ebay. But than again, I think 250€ more justifies the upgrade to the 6S with all of its features and future proofness with its A9. The A8 was IMHO not that much of an upgrade over the 5S's A7, which leads to the last possibility: a 32 or 64GB 5S for about 400-450€. Except screen size, I think that the iPhone 6 has not much more to offer than the 5S. ANother advantage would be that I could keep my cases and mounts which would save me another 50-70€. But how long would the 5S keep me happy enough before wanting something new again, 1-2 years? I don't know. On one day I'm almost convinced to just buy the 6S and be done with it for 3-4 years maybe, on the other day I just think to keep my 5 till it falls apart. But then I would not get anything from selling the 5 and the cost would be even higher. Now I get around 200€ for the 5 which is in good condition and was swapped out by apple in 2014. What would you do in my situation? 850€ for 6S, 600€ for 6 or 400€ for 5S. Thanks for your Input!
