Remarkable 1 user here from the early times - I use it mainly as markup-able pdf reader, with the desktop sync app - for pulling up datasheets that I don’t want to printout when at the workbench. Only reason I don’t use it more widely is the usb-micro plug, (current models are usb-c).
Encouraging to see companies outside the vertically integrated tech giants delivering solid hardware with polished SW/integrations. Shame about the subscriptions but at least for motivated hardware hackers out there, are some good efforts being put in for jailbreaking and sideloading on the current models.
