I just ordered the 10.3" Kobo Elipsa (https://us.kobobooks.com/products/kobo-elipsa) to read research papers on. With a coupon it's down to $310 right now.
I ended up getting a Remarkable 2, and while I think the subscription model is… ehh, I’m not bound by it, and haven’t run into any scenarios where I actually need it. From a hardware perspective it has worked significantly better than the Elipsa did.
I don’t mean to take the wind out of your sails, just giving my anecdotal experience.
I also saw that a new software update made the elipse much more responsive and from a detailed review that i saw it has one of the better eink displays (high refresh rate and no banding)
