Their hardware is top notch, but I found the software to be so hamstrung that I returned mine after a few weeks. Basically, if you want to have exactly a physical paper notebook experience but with a computer, it’s great. If you’d like to transcend the limitations of a paper notebook and take advantage of the nice hardware to organize your work, or do literally anything but write or draw, you’ll be sorely disappointed.
My car has four wheels, that doesn't make it a good ice-cream van
Well, same here: a Remarkable tablet is nearly identical to a Kobo or Kindle in form factor and basic capabilities. It even includes an ereader app. But the app, frankly, sucks. They could swapped in KOreader and called it a day. But instead of that, they — or rather, their supporters — give the laughable excuse that “it’s not an ereader”. Well, an iPad’s also not a calculator, and yet…
If your car has four wheels, room to walk around inside, and built in refrigerators that are mounted upside down for some reason, maybe the factory would say that they didn’t sell you an ice cream truck, but everyone else looking at it is going to wonder why they didn’t make it possible to stock popsicles while they were at it.
I'm not sure what the "ereader app" is that you refer to. reMarkables come with exactly one app "xochitl" that handles all user interaction. Sure, they let you access PDFs to annotate - but again the primary use case isn't to read them. ePub files are consciously converted into PDFs to support that premise.
KOreader, whilst an excellent reading app, doesn't support annotations. So it's not obvious why reMarkable would consider that an enhancement given the primary device purpose.
My car doesn't have space to walk around, nor refrigerators. That's why I bought it. Same with reMarkable devices. I buy and use them for the content creation functionality. I have a Kindle for the times when I want to swap to "consumer mode"
That’s the baseline I’d expect from an e-ink tablet. It might not blow me away, but should at least be reasonably useful as a reader. Any tablet that can’t adequately let me comfortably read an epub is unserious, in my opinion.
