UMS firmware will allow to record with 96kbps at max (from any source - radio, mic, line-in) and transfer will be slightly slower (ie. copying MP3 files to player will be slower)...
but player will be recognised just as pendrive is, no additional program is needed (well... there are drivers, but only for win98 - other systems do not need any drivers)
you decide... and whic version? the newest one ;]

1.85 if you want UMS or 1.65 if you want IMM (this is the same firmware, do not look at numbers
)
and one more "but" - if everything is "just ok" for you... maybe you do not need upgrading?
