You don't understand. I'm not saying that musicians don't care about sound quality. What I am saying is that judging
seriousness by the price of your gear is a giant pile of bullshit.
More specifically, I'm saying I think doing so is a part of what keeps people out of making music--the idea that you have to be "serious" about it by spending a lot of money on recording gear or it somehow doesn't count. Far too often it's just the opposite: people just blow money on the gear because buying things is fun and they tell themselves they need it to make better music. And hey, maybe people will end up buying some iPads for that stupid reason, too. The point is that the cost of the gear and "seriousness" are not so directly related. I don't mean there is never a relation, only that you can't really draw this kind of generalized meritocratic conclusion about the art and artist from something so independent of their actual merit as the tools they use.
You may think it's snobbish, but that's reality in the pro music world.
Again, I wasn't saying that desiring the best sound quality is snobbish. What I think is snobbish is assuming that only professional musicians are serious, or that someone who involves an iPad in their musical process is somehow inherently less serious than one who doesn't.
