The deal breakers for me are the 1500mAh battery and the 32GB memory, although I don't listen to audiobooks. However, I wonder if the 32GB memory actually works, because on my Aura H2O (ver1), if I load more than 1000 books via Calibre, the device starts to crash frequently.

The main culprit is the KoboReader.sqlite file which gets too big (300+MB) so it's corrupted frequently. It's so bad that I have to limit the numbers of ebooks on my device to under 500 books (which use less than 1GB of memory) and turn off the epub->kepub auto conversion feature (i.e. untick Enable Extended Kobo feature in the KoboTouchExtended)

I wonder if the Libra H2O or later H2O versions have this same problem.
1000 books is not very many. I have about 9000 on my Clara HD with no issues. A 300MB database seems a bit big. The Clara HD is less than 200MB when I checked recently. Unless you have a lot of annotations and very long descriptions, I don't know how that can be. You could try compressing it and see if that helps. But, I'm fairly sure I have had over 2000 books an all of my devices, including the Aura H2O, at one time or another without any issues (maybe not the Touch as it does not have much storage).

I would actually wonder if this is a sign the SD card in the device is failing. There are plenty of reports like this which are fixed by replacing the SD card. I had something similar with the Glo. Putting a new card in it made it like new.

And why is the 1500mAh battery a deal breaker? That is what is in your Aura H2O. Or have I misunderstood your use of "deal breaker"? Usually it means something that prevents a deal from being made. But, the rest of the sentence sort of suggests the opposite.
