Playing around with the Preferences panel in Ubuntu 6.06, I found an interesting set of options. In the Removable Drives and Media applet, in the Input Devices tab:

Yes, it is a fairly benign UI that lets you set a script/program to run when you connect (aka "hotplug") a keyboard or mouse. Maybe I am incredibily dense but I cannot think of a program anyone would want to run when hotplugging a keyboard or a mouse...
I am sure it is a godsend for those who need it, but how many people really need it? Does it really need its own UI? From the desktop where "sensible defaults" means removal of useful, commonly used options, the same desktop where you need to go messing around with GConf to configure Nautilus to use a non-spatial interface--the presence of this kind of thing does not seem very consistent.
Yes, I am hating on GNOME. GNOME is very slick and polished in Ubuntu, but it still suffers the problems (that its developers deliberately mandate) that make most classic UNIX users (including me) leave it in droves.
The novelty is nice though, just like when I first used Apple's OS X. But I'm sorry, regardless of how much you hype it, it doesn't stop it from sucking (though sheep--er users of Apple's products like to "think different"). I'm timing how long it takes me to give up and switch to the KDE desktop provided by Kubuntu.
