The Onyx BOOX Tab Ultra C Pro is a 10.3 inch tablet with an E Ink Kaleido 3 color display, support for pen and keyboard input, a 16MP rear camera, and Android-based software that lets you use the device for reading, taking notes, or running a large number of third-party apps.
In other words, it’s a lot like the Onyx BOOX Tab Ultra C that was released earlier this year. But the new model has a faster processor, more memory, a newer operating system, and a keyboard with a built-in trackpad.
Considering that the “Pro” model costs just $50 more than the original, those seem like some decent upgrades. But there is at least one down side: the Onyx BOOX Tab Ultra C Pro has a smaller battery than the non-Pro model.
That does make the new model a little thinner and lighter, but the difference is negligible. The company doesn’t make any claims about battery life for either model, so it’s possible that the new processor brings efficiency improvements to help offset the lower battery capacity, but we may have to wait for real-world reviews before we can draw any conclusions about the impact of the smaller battery.
It’s also worth keeping in mind that neither device is cheap, with the Onyx BOOX Tab Ultra C selling for $600 while the Onyx BOOX Tab Ultra C Pro goes for $650. Those prices include a pressure-sensitive stylus, but you’ll have to pay extra if you want the optional keyboard.
