Is iPhone 5 and iPhone 4s still worth buying?

I heard that Apple will cut the support to iPhone 4s, iPhone 5 and 5c it's that true? Does that mean that if I buy iPhone older models then I can no longer download apps from Apple app store? I would still like to buy it over newer iPhones because how cheap they are now and I haven't had iPhone experience... show more I heard that Apple will cut the support to iPhone 4s, iPhone 5 and 5c it's that true?

I would still like to buy it over newer iPhones because how cheap they are now and I haven't had iPhone experience before?
