Personally i'd plump for a 256meg smart media unit using Js's calculations thats at least 80 average 3 minute songs, I find it hard to jog for more than 30 mins anyway...
Maybe Js, their optimistic figure was based on "Spit spit" hush my mouth... MP3PRO encoding... Yuk!
Nice link, thanks its the way music HAS to go, mobile music anyway... wonder what the RIAA will think of this?
Snark..
