Apple's Outdated Products Getting slow?

I've heard rumors that whenever apple releases a new iphone or ipod older versions start to gradually get slower. So thats what i've heard what do you think?

All technological products tend to slow down after a couple of years.

Also new apple devices can run the new iOS versions better than older ones. IPhone 5s running iOS 7.0.4 will perform better than iPhone 4s running iOS 7.0.4

  • Would i phone 5s get outdated and looked down as like the iphone 4? I want to buy an iphone because i Really need a new phone at the moment but i'm afraid that by next year they'll bring out an even better totally different one and what should i dooo.
  • Will the IPhone that's gonna be released in 2019 slow down after a few years like all the other Apple products? Ever since the news that Apple has purposefully made it so their devices slowly starts working worse as time goes by I haven't bought another Apple product but I really need a new phone, I wish I could buy another phone like Samsung but I have information on my current phone for school that can't be transferred. So I have been waiting for an Apple phone that won't slow down over time, so I don't have to constantly buy new phones and waste thousands.
  • Will the iPhone 4s become outdated soon? I'm an Android user that soon wants to switch to an iPhone. I've been hearing things about the iPhone 4 being outdated. Like updates or major gaming won't work on it. I'm planning on getting the iPhone 4s, but I'm worried it will soon too become outdated? Should I just pay the extra money for a 5?
  • Why is everybody saying the iPhone 4S outdated? In less your going to buy my stuff don't judge on what product I want of course there are the newer iphone models on the market so what? But I just like the more stylish looking iPhone 4S honestly the more upgraded ones are a waste of money
