Guys, reMarkable 2, which is amazing and I use it ALL THE TIME is now $40 off. Here is an affiliate link.
If you are unsure whether you want it, you can order it, test it, and return it for free within 30 days. But be prepared that you will fall in love with your reMarkable 2 and will not want to return it. Ever.
I use it for my to-do lists, random notes, writing blog posts, and for sketching.
