I' go for the mobile unless you eed the space, i have a 40 gig iPod and a 250 gig maxtor and i must say i find my iPod a whole lot more useful because i can take it anywhere easily, while the maxtor just sits on my desk.
the 2oo gb needing a power supply takes away any sort of portability, if this is an aimportant feature fore you, go with the 80 gb, cause youll regret having to carry around an hd and seperate plug, especially that big plug that lacie uses.
