I wish I still had mine. What those units do, they did quite well, once it became possible to back up your data (floppy or serial). Levelstar tried to create a modern equivalent, but the Braille Plus 18 is nowhere near as responsive or task reliable. Perhaps Marc made a mistake trying to go with Android instead of sticking with native Linux as he had with the Icon. The Icon actually came close, but it had a serious hardware flaw, namely that long proprietary USB connector port that weakens from weight over time. And, the Icon has no braille display. The BP was supposed to add that, but it also brought the good and the bad of Android. Now I have a BP18 I almost never use, though it's display is quite nice braille. And, my Icon sits in a drawer unrechargeable. Janina Kirk Reiser writes: > Just as a point of interest, my wife uses her braillite-40 > everyday.
