OK, this is almost definitely unsanctioned by Apple, but the prominent Torrent Web site Demonoid has posted the software for Apple Store's Concierge.
Any visitor to the Genius Bar in recent months will recognize its familiar interface as they waited a half-hour to have their iPod reset. It's an elegant appointment-making solution, and now you can do it in your own home.
Granted, the value of this is a bit limited – why not use a Web browser to make that appointment? – but I say, there's no point to being a Mac user if you can't use semi-bootleg software with absurdly nice interfaces to do things anyone else would cruise to a Web site for!
ifoAppleStore, which brought this to my attention, advises that DesktopButtons, the app behind Concierge, is secretly the $4 wonder Docktop. So check it out.
