Marco, I agrewee that braille dedicated devices are a necessaty tool. I've found that in order to pursue to become a certified special education teacher and a certified teacherof the blind that my education was only enhanced since I had the use a braille note taker. I also benefit from both speech and braille and would findit difficult to depend y on speech output. For this reason, I am glad that I have a note taker with a braille display, speech output anda a add on gps application. Sara Rooz
