The biggest win is not caring if I get the reader back on the charger before I drift off, which is a thing I need to do with my phone.
Also, for anyone that wants to cut doom scrolling, just delete your accounts and delete the apps for the services you're not using in a way you like. In many cases, it's that simple.
Love e-readers though. I've carried one with me (when I had a reason to expect at least 30 minutes of downtime) for a few years now and it's a lot more convenient than the paperbacks I used to lug around.
But also, I didn't understand how much the lightness is amazing. A kindle is light and one handable but it's noticable, this is so light I just can hold it up. I've heard in the ultralight mouse (for gaming), there's a point you just feel like you're moving your hand and don't notice the mouse. This is how I feel for this and it's worth something
