The entire benefit and excitement about the Hi-MD lineup is the ability to get the information recorded onto onto another medium while still digital... ie no further processing. If the headphone output of a minidisc recorder combined with the analog input jack and subsequent A/D process of your standard SoundBlaster soundcard are satisfactory to you then there's no real discussion here. The compression that the older minidisc units use is quite effective in reproducing decent sounding tonal information but the soundstage is non-existent! With the ability to write uncompressed data it's now possible to have a portable MD unit capture enough information to preserve a true 3 dimensional soundsatge! We're really talking about taking MD to the next level in it's ability to record and transfer high quality sound. The transfer process is a vital part of that step!!
You're right though, getting the data out of the unit is not really a problem, it's about the condition of that data after the transfer.
