Installer did this since sarge (for audio, video, cdrom, floppy, plugdev, 
dialout, dip and similar), iirc. By the way, this is done only for the user 
you create during installation. If you create a new user manually, you also 
have to add to the groups manually. Do you select the desktop task in 
tasksel?

I'm not really sure about 'powerdev' group, it's pretty new. But I believe 
Etch installer should definitely add the user to this group when you 
choose 'laptop' task.

Making permissions 777 you sacrifice security for "ease of use" and 
convinience. It's your choice.

It will make your user more powerful. E.g. if you add your user to the 
group 'disk', you (or other process running with the rights of your user) 
potentially can do much harm without a warning, e.g.:

$ dd if=/dev/zero of=/dev/<your hard disk here>

Other than weakened security, there should be no consiquences adding a user to 
a system group. Unless the group is very specialized.
