I have a question about the functions before buying the M92. I read somewhere that you can use instant dictionary by pointing to a word with stylus when reading pdf files. Is it possible though to use joystick instead of stylus to search dictionary (like in kindle keyboard)? Since there are new firmwares, I do not know if this function is integrated. I personally prefer not having to use the stylus when reading.
Also, would firmwares of M92 work on the M92S ?
