In reading my review and other reviews, keep in mind that each person buys this unit with different expectations and uses, and what matters to one person may be irrelevant to another. With that perspective in mind, let me go over the features that I like.
The TX has a nice feel and appearance;the stylus is nicely weighted and fits snugly in the slot. The color screen is vivid and beautiful to look at. I read literally dozens of e-books each year, so screen resolution and brightness are important to me. The TX excels. Even when the brightness is dimmed to the lowest setting, which I sometimes do when reading in bed at night, reading is very easy.
