bluetooth is also almost essential for me:
- in the car to play the music in the phone and to answer phone calls
- with headsets (sony btw :P) very frequently
- with Bluetooth speakers
- with my pebble watch

I will buy likely the sailfishX but cannot depart from another phone until Bluetooth is available. However I am confident that it will eventually come and without waiting too long, but I am definitely supporting them (as usual)
