I prefer xp-pro because it allows you to use it over remote desktop.
As to whether that feature is needed on a laptop is your choice.

For the 2D realm it'll make no noticeable difference. If 3D's your
bag (basically games) then integrated video is pretty hopeless. On
the brightside integrated video will increase battery life which is
always a bonus.

Probably not. I suspect it means you can connect the laptop to a VGA
monitor, or TV with S-Video input. Note that while S-Video is OK for
watching a film, it's hopeless for actual work (unless you like
headaches).

Unless you can bump it up to a 4Mb cache version, I doubt the extra
$100's for a few MHz is going to make all that much difference. 2GB
memory is about the most that XP can reasonably handle anyway, unless
you fancy playing with 64bit linux which is always an option (hint -
repartition the drives and reinstall windows the second you get the
laptop if you are even considering this option).

Dunno - the biggest difference I've found with a dual core machine is
that I can continue working thanks to the second processor. Now I'm
not waiting for it to finish all the time, I care a good bit less
about how long it takes.
