我思故我在 Cogito ergo sum

Coding on Bigme 251 with a delicious lunch lovingly prepared by my wife I've had the Bigme 251 for over two weeks now. During this time, I've had enough daily time to conduct a personal experiment on eye strain, testing whether using this screen for extended periods of work and study with the frontlight on causes any eye discomfort. My theory is, as long as the frontlight intensity is properly adjusted so that the light from the e-paper screen doesn't exceed the ambient light, using a color e-paper with frontlight on is just as eye-friendly as using a black-and-white e-paper without frontlight.

Two years ago, when Onyx launched the Tab Ultra C (TUC), a 10-inch color E Ink tablet with BSR fast refresh technology, I was really looking forward to the day I could get my hands on a 13.3-inch color Kaleido 3 large-screen tablet. After all, the 13.3-inch size is the most suitable for reading A4-sized documents, such as literatures or magazines, and also provides enough writing space for handwritten notes. Furthermore, after the release of the Ta...
