Signature Editions?

Guitar makers have been making 'Signature Edition' guitars (special models endorsed by famous players) for a long time, and for a long time, guitar buyers have been complaining about them...

These complaints seem to break down into some variation of the following:

Why'd they give *HIM* a signature model?
I hate [some aspect] of the guitar
It's sooo expensive

Just the other day Martin announced a new John Mayer signature edition, prompting this posting on the Martin Guitar Forum:

Didn't the other Mayer edition come out just a few years ago? Do we really need two Mayer editions? [...] what has he done to really merit two signature editions?

Well, here's an interesting Signature Edition from Gibson: the Kiefer Sutherland Special Edition

I was really wondering about that one, but then on reading the article I see that he owns about 50 Gibsons, and he has a record label too!

Gosh...well...still. I can't imagine what they're saying about that over on the Gibson forums!
