Some older laptops (pre-ACPI) support only APM. Some new laptops
(post-APM) only support ACPI.
In between there have been many laptops which support ACPI to a limited
extent, and APM quite well, and probably all of the variations in
between.
If you buy a new laptop now it is quite likely that you will be forced
to use ACPI but my laptop (for example) I choose to use APM because the
support is mature (and why would I want to press the power button anyway
:-)
Cheers,
Andrew.
