For my primary use: a portable library, 16 GB onboard storage was simply too little. The BOOX Max Lumi offered 64 GB, and the Lumi II has 128 GB, which I could really use, and ultimately I'd prefer more still.

Remarkable has since shifted to a cloud/subscription business model, which makes me happier for my choice.

I'd prefer Linux under the hood, really. But not with the senseless HW sacrifices that Remarkable are imposing.

I'll add that Onyx's post-purchase support of the platform has been refreshing after Samsung devices that saw no updates at all. There've been about 4--5 in a year and a half, including specifically addressing issues I'd reported.
