As with things that were once akin to wizardry, the BeoSound 9000 has been around so long (and so often imitated) that it fails to excite most visitors.
The BeoSound 5 looks so enticing sitting there with its glossy black screen and, as Steph said, when people spin the wheel and see covers or titles spin around so smoothly and mechanically rendered it's love at first sight.
I personally love my BeoSound 5 in ways I've never loved my BeoSound 9000!
There is scarcely anything in this world that some man cannot make a little worse and sell a little more cheaply. The person who buys on price alone is this man's lawful prey. - John Ruskin
