That may be true for you, but I wonder if you analyzed how you actually use a small capacity device in day to day activity if you wouldn't realize that you hardly used the display on such a limited number of songs.
Plus, the shuffle has a form factor like the common usb key drive that these other flash drive players don't have. So, you need a cable to transfer data between computers with other players.
Personally, since I carry a dell usb drive w/ me at work - I would prefer the option to swap that out with a unit that has 100 songs, is mac/pc agnostic, has a headphone jack and control wheel, than have a display that gets used maybe 0.5% of the time. Music when stuck in the lab, plus an easy way to get some data out on non-networked machines. The wife won't miss a display while running on the treadmill either.
Seriously, if you manage your songs with iTunes - you shouldn't have any dogs on the player anyway and if order was important - you could easily make a playlist. Do you really EVER listen to a song - then hunt for a new one with display - listen to it - then repeat, ad nausem? Who does that?
