These small e-readers are cool, but I think 3.97" is way too small.

I still really like my Kobo Clara BW.

I love the idea of an ereader but I do most of my reading online on websites like spacebattles and royalroad. Would I be able to use this for that, through wifi of course? Or should I just stick with my phone/pc.

Too small, but I'm seriously considering the Boox Palma 3 as an "always in my pocket" offline e-reader and MP3 player. I could do that with retired smartphones, but the e-Ink screens are so nice.

I expect one the size of a micro SD any day now.

Expensive but I recently saw e-ink tokens and love this new innovation https://www.backerkit.com/projects/lynxteam/electronic-e-ink-token-for-magic-the-gathering

Ill stick to having physical normal tcg card tokens vs drawing them with the white board erasables.
