Kobo Forma video review, in Italian, complete with teardown:
https://www.youtube.com/watch?v=gnJrtZ8VYaI
Some info:
- Very easy to hold and very light, so much that it "seems fake"; can be held for hours without problems.
- Easy to open, the back snaps off on one side and is glued on the other (as you can see in the video). Has a water-resistant protection coat on the circuitboard inside, and the memory is soldered so it can't be replaced. Also, there's a "honeycomb" metal shield between the board and the screen, which makes it quite resistant.
- The reviewer's opinion "as an expert" (i.e. nitpicky): excellent device, very easy to use with excellent lighting and better than the Aura One (especially for comics reading); the lack of performance upgrade disappointing, for PDF support in particular, which is still lacking compared to the Oasis 2 and should probably been improved considering the larger screen. Praises for the increased "immersion" factor (really easy to lose yourself into the book and "forget" about the reader).
- Battery more or less on the same level as the Aura One: he estimates one week for heavy users (3 hours of usage a day) and 3 weeks for regular users (1/1 and a half hours of usage a day).
