Boox has more resolution at 2480 x 1860 pixels (1872×1404 for Inknote) while the Bigme has more colors with over 5000 colors compared to the Tab Ultra’s 4096. That’s because Bigme has developed technology that utilizes accumulated optimization processing to display a wider gamut of colors.
There are some differences in hardware specs to as Inknote has 6 GB of RAM while Tab is 4GB. But Boox has a bigger battery though at a whopping 6300 mAH compared to Bigme’s 4000. They both have an octa-core processor and a generous 128GB storage with an option to expand via micro SD- so no storage problems in any of them.
The reviews of the Inknote color on their website are not very reassuring though as there are three and they all are negative. The main issue is that the tab is not primed for international use when it comes to the 4g network and language which leads to problems such as in Handwriting to text. You can read them yourself on their website. As for the Boox Tab Ultra C, there are no reviews yet as customers will get the device a week from now on the first week of May but you can pre-order it from their shop today.
