I purchased the recorder for the same reasons! Recording elderly relatives... music concerts, etc. 1- yes, it is right for it. 2- yes, you can upload it only once, but why would you want it sitting on the minidisc anyway? what I do is upload it as 'wav', splice it however I want (get rid of the garbage), save, then convert to mp3 in itunes or in my audio editing program (adobe audition) 3- that's real-time uploading, where you basically play the file and the computer captures what you're hearing. that's always going to be possible. however, USB offers much faster uploading, but again, you can do that only once. the worst case scenario ever is that you will have to upload in real-time, rather than quickly through USB. 4- once you get the 'wav' file, and/or convert it to mp3, just transfer it over to your non hi-md as normal. the major advantage of rh-910 is the usb direct upload basically... you NEED a good microphone to go along with this. i /highly/ recommend the sp-bmc3... best bang for your buck: http://www.minidisco.com/sp-bmc3.html order it from online. you can clip it onto just about anything, and if you're doing surreptitious recording, you can have it underneath your clothing and clip out onto your sleeves... and the quality is stupendous!
