Dave, I'm guessing you haven't used one ?
Until I used them I think I felt the same - now I think there are plenty of applications where they are actually pretty useful. I think it's fairly obvious that wouldn't be your first choice for a micing a drum kit, but now I'd have no problem recommending one for a more casual or technophobic user.
It's horses for courses and about finding the RIGHT to for the job - that's not always about the most flexible or 'upgradable'
Taking a look at few SOS reviews from the last month

seems like the market thinks they are a good idea too.
I can assure you that all the actors in that read through were delighted - and nobody's Mums were involved. I'm guessing you're not going to change your mind though.
