As BB's said, depends on your budget and purpose for them, SB. I've got a
Logic3 i-Station (mine's in black) which does the job well enough when travelling. Folds up into a neat, compact unit and has a decent enough sound to it. I'd imagine you'll find it a few quid cheaper than that if you shop around as well.
I've no real need for a dock at home - all my music plays direct through my hi-fi and floor-standing speakers - but if I were buying a dock unit for the home and my budget allowed for it, I'd probably go for the
B&W Zeppelin and leave the Bose stuff well alone as they're more about marketing than sound.
