“The Onyx Boox Tab X C has one of the largest color E Ink displays you'll find and it comes with a high-quality stylus. It's also underpowered and has shorter battery life than competing ereaders, which makes it a bit tough to recommend.”

“You have to really want an e-ink screen to justify buying this. You have to really want, specifically, a device that costs as much as or more than a tablet that specializes in reading and writing/drawing, and nothing else. If that is what you want, then yes, the Boox Tab X C is a fantastic choice, with a good tactile writing feel, enormous screen, and all the benefits that an e-ink screen provides. But it's expensive for how niche its specialization is, so I can only recommend it to people who want that specialization and nothing else. If you want a tablet device that can do anything a laptop can do as well as that laptop, you'll want to spend your $820 on something else.”

“It's clearly trying to be a competitor to the iPad, though it definitely isn't. Even with a keyboard, it still feels like a supplementary device, not a replacement. Casual readers won't want to hold the device for long periods of time. The size makes it awkward for novels, and cheaper eReaders — including many from Boox's own lineup — handle that role far more comfortably. If you're primarily going to be reading things like novels or similarly sized small books, I suggest the Boox Go 7. It is perfectly sized to mimic holding a paperback.”

“It's a great digital notebook with the largest color e-ink screen on the market. It's also pretty dang expensive.”
