When I reported on the Libra H2O going up for pre-order last week, I said it was available through Walmart. That was a reflexive goof, but now it is actually true.
The Kobo Libra H2O has a 7" Carta E-ink screen with a color-shifting frontlight and a waterproof rating of IPX8. Walmart is selling both the white and the black models for $169, with free next day delivery.
That makes it hard to bot buy them (Kobo won't let US residents use its site) and it also makes it hard to try the devices in store. As a rule, Walmart only stocks one or two Kobo devices in stores, and they have never actually finished setting up the Kobo displays in any of the stores I have visited.
But on the plus side, at least the new device is available.
