WinXP SP2 Curious Question

As far as I can tell, there's nothing new GUI-wise except for the new Windows Firewall Settings. But I have to admit, I haven't yet actively looked for the changes that were made by SP2...

There's also the new icon and GUI for wireless connections, the new pop-upblocker for IE (which i don't use unless it's necessary for Windows Update), and a new Wireless Network Setup Wizard, but everything that really important, you'll never notice it, except for the firewall alerts.

What's really annoying is that, in FireFox 1.0PR, they decided to make popup blocking look like it does in the IE included with XP SP2. Personally, I liked it better the old way, with just the icon in the status bar, rather than stealing my on-screen real estate.
