I can't believe that i am looking at Alienware laptops and starting to drool. Maybe I am just falling for the looks and the cool gaming specs I don't know. But I do know that the few things that get my blood pumping are the:
(1) Dual 2.5 inch Hard Disk Drives and the plethora of configs for them. Raid 0 to get up to 500GB with the Western Digital drives or 400GB @ 7200 rpm.

Freaking WOW man... that is just the best thing ever... As an editor the idea of having a scratch disk running at 7200 rpm with 200GB of space and a system drive at the same size and speed is just a dream come true. I would never need an external drive again.
(2) The SLI graphics from nVidia. I like the idea of having a Gigabyte of graphics memory at my disposal. I am not a hardware nut that can spit random facts about what is current what is this and that. All I do know is that they say a Gig, and my eyes bug out.
(3) The average cute stuff that doesn't really help with productivity but really helps when you just want to play around and have fun. Built-in DVR, a full sized keyboard and number pad (with all of that space they could fit one), and that freakin GIG OF Graphics MEMORY!!
I still love the 17 inch, and when my current book gets too old, slow, broken, warranty runs out, whatever I will get the next real update to the MacBook Pro and I hope that Apple puts more than one drive in the 17" book and maybe some serious gamer graphics. The current book is wonderful, but I was too expecting some more innovation, not just a Santa Claus chip and some usual upgrades. But that is okay for me.... Apple will give us some new hardware for real productivity soon. Not in October, maybe not even in April in next year, but they will give it.
