@ndw I was totally aware of it (and other e-ink products generally) but had not considered it for myself (until a friend sold his) because I already own an iPad and I thought it would be a waste of coin/material and frivolous.
BUT, it's not. It's really convenient and quite portable too (but works only in daylight of course).
Directories (including nested sub-directories) and labels make it a useful and versatile "pensieve".
The #remarkable2 marketing argument "distraction free" is also true.
