Over the years my use of Bluetooth for various purposes has significantly diminished. With the advent of Wi-Fi tethering that I wished for back in 2006 when the first phones with Wi-Fi connectivity were pioneered by Nokia (see here and here) and a few years later realized on the Android platform, my Bluetooth use became occasional at best. I tried Bluetooth headsets every now and then but was always disappointed with their range and I just don't listen often enough to music on my smartphone to have made it worthwhile to buy a Bluetooth enabled stereo headset. Also for transferring pictures or files from mobile devices to my PC or vice versa, Bluetooth was mostly not an option because I always needed a dongle on the PC side. The time this takes was usually the same as removing the SD card from the smartphone and inserting it into the PC or plugging in a cable to access the pictures from the simulated SD card provided by the generic SD card driver that Android provides. My new PC, however, now provides for the first time a built-in Bluetooth transmitter and due to no longer having to plug-in anything, I have found myself using Bluetooth again for quickly moving files and images back and forth if there is only one or two files or images involved in the transfer. A late renaissance of the technology as Wi-Fi direct still doesn't seem to take hold (see here, here and here).
