Got to say, e-ink is an impressive tech...... this has been on "screen" since the anniversary weekend floods, where it got wet.

Its dead, wont charge/respond to anything (claimed under insurance).

You'd swear the thing was fine.... :)

Excellent choice of book to freeze the screen on. I'd imagine they could cut down on warranty claims if the default error screen suggested you'd just been reading 50 Shades of Twilight or some such.

And will basically stay there forever.....

E-ink doesn't draw power for the display, it draws power to "flip" the pixels between Black and White,, so the pixels will stay that way until they are changed.....

That's how E-Ink works. The screen only consumes energy when changing the state of pixels. No change, no energy consumption. My wife's old kobo hasn't been charged in over 18 months and the Micro USB port is broken but the screen still displays the home screen.

Kobo's waterproof models are rated for an hour submerged. I gather that isn't one of them or it was submerged longer.

No, ClaraHD... the 2E is waterproof which is what I'll be getting to replace it :)

Not forever. A few months and it will start to fade to grey. They do say that leaving an image for months will also permanently damage the screen.

Still a great technology. :)

Missing reading, so will be happy once insurance hurrys up and pays out...
