My All-New Kindle Oasis—the just-released waterproof version—hasn’t arrived yet.

But here’s a video review by Len Edgerly of the Kindle Chronicles. Read his related text post: What’s great about the new Kindle Oasis and what I miss about the original.

Yes, the Kindle and the ebook Len was reading survived an ocean dunking just fine. Not everyone prefers the new Oasis, though. As you’ll see from the reader comments on YouTube, some still favor the old one with the detachable auxiliary battery to keep weight to a minimum.

But I myself would rather not mess with removing and reinserting the battery, and I’m looking forward to newer Oasis’s seven-inch screen, an inch bigger than the earlier model’s. What do you think about the new model vs. the old one?

Meanwhile here’s an excerpt from Len’s review:

As for the larger screen, sometimes I like it and sometimes I don’t. Bedtime reading seems better with the original Oasis, which is smaller and lighter. The seven-inch Oasis screen seems to be shouting at me, sending me more words than I am used to as I read calmly before sleep. But reading in the living room, when I am perhaps more alert, I enjoy the larger screen real estate.

The off-center balance of the new Oasis is even more pronounced than that of the original, because there is more battery weight in the new one. It’s a good feel, like reading a paperback book in one hand

Now that Amazon has addressed the water issue, how about some drop-proofing—especially considering the newest Kindle’s $250-and-up price tag? For most people, I suspect, drops are a bigger hazard than the water.

I would also welcome more control over line spacing on all Kindle and Fire models.

That said, each improved ereader model makes it harder these days to be a Luddite. Catching up with Kobo, Amazon has already added the all-text bold option for which TeleRead and others campaigned for years. You can also update your existing Oasis or Paperwhite.

Lower prices for Oasis equivalents will follow in time. Trickle-down, as I’ve written, doesn’t work in economics, but in technology, it does.

The All-New Kindle Oasis offers a preview of the cheaper readers that will materialize. What’s more, in the near future, the used market will beckon.

Just so you’ll know: You’re welcome to disagree, but I myself think there’s still life left in dedicated E Ink readers—if for no reason other than that many people find reading off them more comfortable than looking into an LCD screen of the kind found on tablets and phones. What’s more, ereaders like the Oasis come with well-positioned page turn buttons. Cell phone volume controls aren’t always in the optimal locations.
