The battery life was really bad in the first software versions but seems to be a lot better now.
I use it for recipes (I like to write my own version out even when working from a cookbook so that I can modify), UX sketches, and most recently I’ve joined a bookclub and has been great to highlight passages and write notes in the margin for discussion.
Overall it’s been useful, but the early bad experiences with battery life/power management really turned me away from more consistent use (after a couple meetings where it powered down and had to go back to my desk to grab a paper pad).
Would be curious to hear from anyone who got RM2 after RM1 and what their battery life difference has been!
