What I've seen of HAL so far looked very convincing. You get a nice API for 
querying what kind of devices you have in your system and you can query all 
sorts of properties off them (like if it is mounted, the fs usage, whether it 
is a block device). You also get notification when properties change or 
devices get added or removed. And it's not varpourware, it actually works.

It also looks like the right layer to me. For example if someone wants to add 
support for hotplugging in Solaris he could implement that bit in hald and 
KDE and GNOME would see it.
