I was wondering if there was any possible workaround for the lack of a mic input on an N505. The only one that I know of is using something along the lines of a karaoke machine, which captures the mic input and sends it out via line out (I used a karaoke machine with my N505 to record piano music, but it wasnt very portable). Does a pocket version of something like this exist? One that would run off of batteries, have a mic-in port, and a line-out port? It seems logical, and one could probably be made, but im sure they're available somewhere on the internet. Also, I come across battery powered microphones every once in awhile (not too often anymore, actually) Does anyone know if these send out a signal similar to a line out?
