Bluetooth 5 will quadruple the range, double the speed
I could not care less.- 1.0 to 1.2: Hard to pair, and very unreliable. First major version, I'm sure they'll fix it...- 2.0: More bandwidth. Still hard to pair, still unreliable.- 2.1: Adds "Simple Secure Pairing". Still hard to actually pair. Still unreliable.- 3.0: More bandwidth. More features. Still hard to pair, still unreliable.- 4.0: Bluetooth Low Energy released. Still hard to pair, still unreliable.- 4.1: More features. Still hard to pair, still unreliable.- 4.2: More features. Still hard to pair, still unreliable.- 5.0: More range, more bandwidth. Still hard to pair, still unreliable.I have the latest Apple "Magic" Trackpad, hooked up to a Mac Pro. At least once a day, latency will take a dive, or it will completely disconnect. I have to turn the trackpad on and off repeatedly, to see if it will finally re-pair by itself. No other recourse, you can't easily access bluetooth settings on a mac with only a keyboard. (Which I made sure to get with a USB plug, since my last bluetooth keyboard had the same issues.)I also have a Samsung Level BT headset, paired with a Samsung Note 5 phone. I can listen to Google Music or Player.fm for between 1 and 10 minutes until the headset will suddenly blast noise at full volume, and become unresponsive until I turn it off and back on again. Left my ears ringing on more than one occasion.I've replaced my "magic" keyboard with a USB one, and recently hooked the trackpad back up via USB. I've stopped using the Samsung Level and went back to an old pair of headphones with a 3.5mm plug (that Apple is now trying to get rid of.)I had a past without wires. I am moving to a future with them.
