It's worse than that. My gaming PC was top-of-the-line six years ago, and it still works great for browsing and work tasks, and runs many modern games effectively on lower settings. My Samsung Galaxy Nexus phone was top-of-the-line six years ago, and is essentially useless now. Just switching from an app back to the homescreen takes multiple seconds, and launching or switching between apps often takes upwards of 15 seconds. It takes more than half a minute to start Kindle Reader and open a book. These are all things that happened almost instantly when it was new. I've wiped it and reinstalled Android multiple times, and it only helps a little.
