I personally have about the same number of devices as I did through the decades but I have a lot more gadgets. I used to have a cell phone for phone calls and texting, a camera for taking pictures, and a portable audio player (Walkman then Discman then MP3 player) for listening to music. I now own a phone that does all of that, but I also have an 8mp digital camera that takes better pictures and an MP3 player that is more compact and comfortable when I go to the gym. I've never owned a stand-alone GPS but I now have one in my phone. If I had a day-to-day need for a GPS or needed better accuracy for hiking or geocaching I would get one for that purpose. I have never owned a stand-alone handheld gaming system but my phone can do that too. Of course, if I was serious about handheld gaming I'd get something like a PS Vita. When I looked into getting an eReader I ended up with an Android tablet. It works as an eReader plus everything my phone does plus plays HD videos and even hooks up to my TV via HDMI. I bought a Bluetooth dongle for my car and can read engine codes with it. But now I wish I had got a one-trick-pony eReader for the better display and longer battery life.
