I briefly activated the wireless, only to see if it would sync the time, and it did.
The initial charging didn't take that long, but since you said it took yours a while, I was perturbed that my "initial" charge didn't look like it would last 6 days, let alone the advertised [up to] 60 days.
The second charge is lasting much longer.
That ghosting is a real pain. I think it comes from changing pages too fast, as in touching a button/screen inadvertently, and trying to return to the original page immediately. Sometimes, the only way to fix it is to off/on it. Changing apps might make the ghosting worse.
I had no problem setting up wireless. As I stated, the ghosting and the questionable USB issue were the big killers for me. The microSD slot wasn’t an issue as I keep my books on my PC and only keep what I want to read on the reader. I seldom listen to music as it’s a distraction when reading so I don’t need a lot of storage for that. And the only photos I carry are a few recent ones of our granddaughter for showing to friends.
