Still loving this BTW...
i'm not "getting it", and i think it's for the same reason as why i don't need a 80 GB ipod - i don't need access to all my music at all times in all places. my foray into mobile digital music started, and continues, on an ipod nano with 8 GB. i'm used to limiting what music i have with me at any time. i'm typically listening to a few new albums, have a few in my to-be-listened-to queue, and a few old-timers that i dug up (typically EDM music to run/work out to). when i sync my ipod, i have to remove music in order to add new stuff so i'm used to being cut off from part of my music collection while on the go. for me, limiting what i have access to helps to ensure that i get around to listening to everything at least once.
maybe if i start using my phone as a secondary listening device it'll all make sense. or if i'm at a party and i want to pull up a tune.
