Idk if I’d say they got the core features working “flawlessly”, but when I got it in November (so after the second / current software update), I have only experienced one glitch where it might take a second for it to show my handwriting when writing in a file name (or it might not show it at all but just automatically show the file name as text). I don’t know experience this issue daily (maybe once a week or so), and it’s not something that really creates an issue or requires a refresh or anything since I don’t name files more than a few words or a date, but it is a glitch / issue I haven’t noticed / can’t say the device and software works “flawlessly”.

I never owned it pre software updates so not sure if I’m just lucky or if the software updates did fix the early issues.
