What are the checkboxes good for, then? I see their purpose mainly in 
solving the discoverability problem both ctrl/shift and drag 
multiselection have. If you know how to multiselect with ctrl/shift, you 
don't really need checkboxes anymore, do you? So I'd either show them 
always (if multiselect is possible, that is), or never (if selecting 
multiple items is not crucial and therefore it's okay if people don't 
discover it)
