LENOVO SMART PAPER vs BOOX TAB ULTRA C: Which e-ink tablet is best?

This page was created to explore the similarities and differences between two e-ink tablets; the LENOVO SMART PAPER, and the ONYX BOOX TAB ULTRA C.

This is currently a simplified comparison consisting of a table of side-by-side specifications, and review cards of each tablet, outlining their pros and cons. If a tablet has a rating then you can also click on it for a full and detailed review of the tablet.

I do write detailed ‘versus‘ comparisons, however because I am only one person it is impractical for me to compare every single e-ink tablet against every other one! So if you think that this page would benefit from being fleshed out with additional information and my own thoughts and opinions, then feel free to drop me an email at dan@ewritable.com – I will prioritise pages that get the most requests πŸ™‚

I have also created a gigantic e-ink comparison table (which is also searchable/filterable, so you can whittle down your search to the tablets that best meet your needs).

And a list of (what I believe to be) the best e-ink tablets can be found here.

Now, onto the comparison between the LENOVO SMART PAPER and the ONYX BOOX TAB ULTRA C.

Dan Dutton is passionate about E-ink writing tablets, which bring together the pleasure of writing on paper with the power of digital technology. When he bought his first tablet, he realised that there wasn't a lot of unbiased information available for people that were considering buying an E-ink tablet, and so he built eWritable.
