Why does Apple keep making and release new iPhones every few months?

Like why did they make then Iphone 6 just make and release the iPhone 6 plus, iPhone 6s, iPhone 6s plus?

What is the point of apple doing this doesn't apple not have enough money?

It's like if you have windows 7 and you upgrade to windows 8 then they come out with windows 8.1 then a year later they come out with windows 10 like why i already upgraded why do i need to upgrade again?

People are gullible, and will buy any new tech.

Nobody needs to upgrade

I'm still using my iphone 4s 64gb very happily

its still supported and I'm yet to encounter an app I want that won't work on it

Because that is how they make money; keep updating just a little bit of things here and there and charge the full price for it. If anyone is to blame it is the consumers that keep getting in long line and wait for the arrival of the new phone. Car companies also do the same thing.

Bigger-better-more. NEW. If you have 'older' model you are a LOSER. But, seriously? I have the IPhone 5 and can't use all the features it offers. Why on earth do I need something even MORE complicated? But that's me.

  • Why does only my works Wi-Fi keep kicking me off and making me log in and accept terms? I just got a new iPhone and I'm always connected to my home Wi-Fi and any other Wi-Fi is fine. I used to have an android and when I logged in and accepted terms I would be logged in all day. But with this iPhone it kicks me off and brings up the log in screen every time I use my phone! Help! And btw my works Wi-Fi is good I work at a well known hospital in San Diego.
  • Why does apple release a new iphone every year? I don't think it's fair. We all spend so much on a new iphone and find out a new one s coming out next year… It just really annoys me!
  • Why does Apple keep releasing new products every year? Why does Apple keep releasing new versions of the iPhone every year? Sometimes the newer version really doesn't make a difference from the older version. Also am I the only one who hates it when they release new versions of the iPhone? Like I want to an iPhone but I'm scared that they'll come out with a new one making mine look old even though I just bought it. Woah! There's no need to throw unnecessary hate in my direction. Mmmkay
  • My iphone keeps on flashing and locking by itself every few seconds? Since 5 hours ago my iphone 5 has been flashing every 10 seconds intervals or so and it will lock by itself and turns on back to the lock screen by itself. It would even flash to the power off screen at times. I've tried syncing, charging and restarting my phone but things won't change. (I've had my phone for almost a year now + the decrease volume button is spoil) should i claim from warranty or are there any way i could resolve this flashing issue by myself?
