I&#x27;ve been using old smartphones for a while now and even phones that were released in 2014 are dirt cheap since for me, there is no discernible differences between models.<p>Can I:<p>1 - Take a picture and post it somewhere<p>2 - Surf the internet and use apps for consuming content<p>3 - Take some video and upload it to youtube<p>4 - use it to text message friends and family<p>5 - make and receive phone calls<p>These 5 basic functions are available on EVERY smartphone manufactured today. The differences? Minute. My LG G2 vs. the LG G3? The LG G3 has a Mildly better screen, 1 more GB of RAM and few other minor improvements.<p>You&#x27;re absolutely correct progress is slowing down in tech. The biggest move forwards I thought was when Microsoft completely redesigned the interface of their Windows phones. It was totally original and I thought much better than how Android copied Apple&#x27;s design.<p>Other than that? Not sure there have really been HUGE tech advancements in the smartphone arena. Same goes for PC&#x27;s and Cars. Unless you&#x27;re a HUGE hardware guy, I don&#x27;t see big improvements or revolutions in these areas of tech.
