Agree mostly, but I think the checkbox was a good idea.
Make the popup have just OK/Cancel.
To break dependencies, make people check a checkbox labelled something 
suitably scary - e.g. "Force installation with broken dependencies" - and 
*then* click Next.

I would really rather not have --expert at all.

Command line options are fine for automation, but in general it is much more 
elegant to allow people to configure such things within the GUI. I know we 
have abused command line options in the past, (e.g. -5 ), when we weren't 
quite sure or didn't have the time to add appropriate stuff to the GUI, but 
I would rather not perpertuate that.
