There's no problem with that setup for standard books too, I just usually prefer a smaller/crappier ereader (ideally also with koreader) for that type of reading.
Bonus: reading black and white comics on a remarkable feels even better than on paper.
Perhaps the epub experience has improved - but I've mostly used it with White Wolf rpg pdfs (granted, they are terrible - almost unreadable even in print) as well as other rpg books - typically large format, two columns - and its awful on the rm2.
In general, only short PDFs are bearable, epubs feel like they should work but they take an incredibly long time to render, which frustrates me every time.
That being said, it's absolutely incredible for writing, but I don't need that as much as I used to (take less notes now as I'm more of an IC than my former team lead/PM/IC hybrid).
It's a shame there's no official way to augment the software with apps or patches - there's community software, but it feels like a really fragile system.
Remarkable screams designed by marketing to me tbh. Features exists to sell, existing customers can suck it.
I really want to like the RM, but it just misses the mark on software quality and performance. UI is clunky and latency _just_ high enough to be anoying to me. I'll probably pre-order the RM3 if that ever comes though :)
Yeah, that is annoying to me. To their credit though, they did make it easy to just install it yourself.
