It's in the sense different to the tulip mania argument that it doesn't aim at the price as an argument.
What this is about is utility. Everybody who owns a TB-303 does so because they are into Acid, a style of electronic music and they want to own an authentic instrument. That is the case because for any other style of music the TB-303 isn't as well suited as other instruments, and hence others aren't willing to pay the market price.
This is also why prices don't crash, even when there is an abundance of alternatives.
With fads people buy stuff because other people did, even if they don't have a reason to own it. Price bubbles are just a symptomatic of the fad-iness, not an argument about systematics.
