Terrific device, worth the cost
I work in sales and take a lot notes, and do a lot of writing on a day to day basis. I had been using some smart notebooks and have tried other electronic means to write and keep track of everything until a coworker mentioned this.
I spent some time looking up reviews and gathering info on the device before trying it out, and after a few weeks of use, I'm very glad I did give it a shot.
Writing feels as close to writing on paper as I've ever tried, and that even includes certain physical "smart" notebooks. Response time is fast and delay is almost non-existent, especially for an e-ink device. Device saves and backs up my writing without any issue, OCR works fairly well even with my garbage handwriting (although not without issue - it's not perfect, but still decent).
Why not 5 star? Battery life *is* a bit worse than you would expect. It's not bad, I get about 2-ish days with constant use, but with such a bare-bones device you'd expect more.
Also, exporting isn't the most ideal - not terrible, but could be more streamlined and easier.
All in all, the pros outweigh the cons, and after spending time with it I do feel as though the device is worth the price.
