10 to 11 was a snap, but 11 to 12 had a few gotchas, especially with fonts.
There are notes what to expect if you go for upgrade path, rather than 
new install.
I had a lot of older dropline gnome libs laying around that caused some 
They are gone now that I use XFCE, and no more issues.

What version of CUPS and gutenprint (aka gimp-print) are you using?
Gutenprint is the new name and 5.11 is working really nice - solved some 
issues with graphics on the HP.

Mostly just apps that were compiled with shared libs.
I've had an odd blowout here or there, especially anything that used 
video drivers.
I usually use apps not in the distro, or recompile the disted version to 
pick up different features,
like with amarok and postgres db usage.

I think they addressed a lot of that in 2.6 kernel.
System processing does seem smoother and less choppy.
I hit hard with compression tools, and playing mp3's, and working in Gimp.
Writing to IDE DVD has not caused any coasters while playing mp3s.
I do notice that I do get bad media from Costco's TDK 100pk, DVD+R, but 
the cheaper DVD-R work flawless.

Some managers run tools to work with Hal and such.  I keep forgetting 
your on 2.4 :)
A lot has changed in 2.6, the hotplug device has been replaced with 
Hal/udev and seems to work much better with recent releases.
Could be the hotplug daemon that is causing you delays.
