Phew, we can now talk about the H2O, finally
Biased as it will seem, I really do like the device. I'd been thinking about getting an Aura HD, but was holding off as I knew there was something else coming along, and it seemed wise to wait to get this new device, rather than the normal Aura HD.
It does actually work when in water, you can turn pages, and I've had first (wet) hand experience of this.
As for use cases, well, how about reading on the beach, or near the pool. there is of course the whole reading in the bath thing too. Another one would be that you're on the deck reading, pop inside to grab a snack and leave the reader on the table and it starts to rain, the device should be quite happy sitting there, without the need for you to run out and grab it.
Am I going to get one? Yes, I'm going to pre-order one. Yes, that does mean I'm going to be buying one with my own cash. It will actually be the first Kobo device I will have purchased (I have had other Kobo devices, but I didn't purchase them) and I think that might show that I'm a little proud of the new device, as I'm willing to spend my own money on it. I know, I know, probably sounds very sickly sweet, but I'm not a sales guy and trying to persuade others to buy.
