I retired from personal blogging in July 2008.
But you can find me over at http://blog.xero.com.

I am on my MacBook. Found this great utility WhatSize, which allows you to see immediately what’s chewing up disk.
I found an 9GB XP image on Parallels which I’m not now using and near 3GB of Entourage 2004 storage not touched since moving to Entourage 2008.
I’m now back to reckless storage.

Omni disk sweeper is also a great app the works in the same way. Some of the big culprits are the hidden .vol files from incomplete burning sessions and .log files that infinite loop errors can swell to tens of gigs.
WhatSize is a great tool. I found some video editing leftovers of roughly 12 GB the other day… As Will said, there are plenty of other space wasters in OS X, particular log files etc. OnyX is pretty handy to keep things clean.
I really like filelight which does this great very simple pie-chart thing - it’s OS, there’s a mac version too
Another similar too for linux is the disk usage analyser (Baobab). It is bundled with Ubuntu and has a lovely pie style chart. http://www.gnome.org/~ebassi/baobab-ringchart.png
I’m too poor to own a mac, but on the pc I use SpaceMonger http://www.werkema.com
http://en.wikipedia.org/wiki/SpaceMonger It gives a quick visual on the space used and is freeware. Nice Blog Rod
For other Mac users who are looking for a free (GPL) solution, Disk Inventory X seems to do the trick pretty well. I’m not sure if there are some features missing, but It seems to do everything you’ve described, and it has a fairly pretty interface to boot:
