	I've never said that, and in fact, I've used apm without a 
single hitch on Thinkpads going back 6-7 years now through 5-6 
different Thinkpad models. It has never caused me trouble (and having 
the author working for the company I worked for at the time, helped 
considerably ;)

	But I was looking for something better, and something that 
would allow me to interface with my UltraBay and DockII. That led me 
to ACPI, and I was hesitant, because I've heard the horror stories 
from people who have used it, and hundreds of reports from frustrated 
users who couldn't get it working at all.

	I decided to give it a go. It burned me, confirming my 
original hesitation in the first place. So now I'm back where I 
started, looking for something that will let me use my UltraBay 
runtime, and talk to peripherals attached to my DockII, without having 
to use Windows, and without having to cold boot each time.

	Suspending to disk is probably amendable, depending on how 
long it really takes to go into and out of suspend. When I suspend, I 
can't be waiting 10 seconds before I close the lid, and I certainly 
can't be waiting 30-45 seconds to bring it out of suspend (especially 
since it does a full boot anyway, including BIOS and grub, I might as 
well just cold boot and relaunch all of my apps, which gnome-session 
does anyway).

	So that leaves me with what? swsusp2, and no UltraBay and no 
DockII support... which means I'm much better off sticking with APM. 
If I'm not going to be able to use those two things anyway... I'd much 
rather have the faster suspend/resume than not.
