I have a Remarkable 2 for notes and working on math problem set homework to hand in as PDFs.
It’s fine. It doesn’t do anything other than record your handwriting. You can try and have it convert it to text, this works for language but fails utterly at math. I got the better pen that you can turn around to use as an eraser as using the UI to change the tool from pen to eraser and back is incredibly annoying.
I recently got an iPad to use instead mostly because I wanted one anyway, and because my handwriting is atrocious and iOS 18 pretties it up. I haven’t quite made up my mind on which one I’ll continue using. The iPad and its pen are more responsive, the fact that it improves my handwriting is a boon for the TAs, and solving some of the simpler math automatically is neat. The built in Notes app is garbage for handing in multi-page PDFs, bafflingly this is impossible, but the Goodnotes app is cheap and rather good. There’s other apps to convert handwritten math into Latex.
The Remarkable produces much smaller file sizes (I’m not sure why I care, the web app I upload homework to sure doesn’t) and the battery lasts much longer. I find replacing the pen tips very annoying and have no idea why that is needed.
I’ll probably end up using the iPad more, but I’ll guess I’ll see.
