Hello,
Seeing more interest piled up here, let me document my knowledge of 4 month (base software + koreader mixed use):
Pros:
- lightweight
- battery: less than 1 week with PDFs, 3 weeks with internal software + eBooks
- reading experience, comparing to my Kobo H2o v2 7": much better to read (I'm above 40) ePubs, eye relief is good (hard to get back to the 7"). For PDFs, the 7" is just unusable compared to this screen! (returning to 7" is like reading through a small hole)
- 32 GB storage (it's a MUST, when you plan read PDFs - they can be large!!!)
- koreader runs...
- ghosting not disturbing (refresh every 6 page), unlike my Kobo 7" that has rather disturbing (in turn, kobo's update is not sluggish)
Cons:
- the device(screen?) is sluggish whenever have to update *ANYTHING* on the screen !! (here comes koreader, one of its biggest advantage to avoid these disasterous screen updates). Note that this sluggishness doesn't affect reading experience of normal text books with a few pictures (either pdf or ePub)
- koreader bugs (
https://www.mobileread.com/forums/sh...d.php?t=329706), hopefully improving with time
- this device is fragile, ***forget about carrying it aways from home*** ! (you still need another smaller eReader for a "pocket" use) Hence, you don't need any case... (won't find, which is not a problem...)
- 2-core is not enoguh for complex PDFs (however, no delay with less complex PDFs - e.g. simple text + few normal pictures in them)
- dictionary software is a mess (doesn't do stemming, have to edit manually... koreader solves it better, in turn koreader dicts are small for my locale)
Cutting margins is still recommended at this screen size, you would need the 13.3" to read PDFs without tweaks.
It depends on type of PDF whether own software, or koreader is better (both software have their own strength/weakness)...
My triggering reason to buy this device was the covid/home office (no commuting, can use larger screen), and already had good experiences with koreader on kobo (now I see, koreader SHOULD be the default software for kobo, they work so perfect together...).
Was looking hard at the 10.3" Onyx (latest device), but I already own tablet (with pen) causing that functionality needless (and to be honest, after a tablet experience, those Onyx devices give me the "almost" feeling, so feared to buy), and battery is a typical mess with android in general (andoroid got fat during the past years, every of their release causing my tablet slower and slower - 8 CPU is a minimum for them).
Only the Onyx is a competitor in my local region (middle Europe), other brands very hard to get. Amazed kobo & kindle still missing this obvious need (10" is much more needed than color).
Summary:
- superior reading experience of ePubs (eye relief) over the smaller screens
- usable for PDFs, but need a very clever use (cut the margins)
