Besides everything else mentioned I won't miss the guilt!  I always felt guilty smoking around my dogs and cats, and I smoked inside the house & car.  Gross, but hey, I pay the mortgage so why go outside?  That was my thinking anyhow.  
Now, I'm new to 
vaping and I've only been smoke free for a few days but I can can totally smell just how gross my house is and can't wait that funk to be gone.
I won't miss the nasty taste in my mouth from an analog and I definitely won't miss having dead taste buds.
