I mean, I will be paying the price because I am do for an upgrade from my 6+.
Am I happy about it, not really but I have my finances in order where I can afford one. Plus the only other major apple purchase I have made recently was the 2016 rMB m5 at a $300 discount. Only two apple products I own (I forgot about the iPod nano 5th gen that sits in my drawer that never gets used). I talked myself out of an apple watch for now because I don't see the point of dropping $300+ for an extension of my phone. This is comparing to some people on here that have thousands of dollars of apple products (not to call anyone out, it's their life wether it befits them business wise or just as an enthusiast).
Apple could jack up the price even more if they wanted to and people will still pay for it. You are paying for more than just the hardware (software, customer service, etc.).
I've rarely had any issues with apple products over the 11 years I have owned them. When I went to the samsung galaxy s3 on a whim because my 4 got stolen 3 days before a trip, I loved the new feel of something different. Down the line, the phone was sent to the factory TWICE for technical issues and I paid far out the ass to get them taken care of.
Apple just works and it works well. It's a premium product that commands the price they are asking for. Another example for me was when the 2016 rMBP were released. I waited several months holding off from buying a rMB because I wanted to see what they would bring to the table. While the touch bar looked awesome, for me and my uses it didn't justify the $500 up-charge. I went with a 2016 rMB and I love this thing!
I am ready for a new phone and have chimed in to the iPhone and Alternative to iOS forums to see what others had to say. Go with the 7+, s8+, or wait it out. For now, I am waiting it out as my almost 3 year old iPhone 6+ has been excellent with one minor repair (camera pin, which they replaced FOR FREE).
