Those of you who love your einks have at it, but the flimsy excuses that you give for not using anything else are kind of lame.
Last I heard you can put any tablet or phone into airplane mode thereby silencing the phone, or notifications that come through, and tablets and phones come in different sizes and weights for just about anyone.
Don't blame the machine for your lack of discipline. It's amazing how many people just forget that machines are here to serve us at our convenience, NOT the other way around.
We all managed to survive just fine without all of it before it came along. My phone stays in airplane mode all the time unless I am traveling or turn on wifi a couple times a month to check for updates.
No one is putting a gun to your head to drop everything right now to answer your phone or check emails.
