Alright, troll. I'll play your game.
Here's an Alienware MX17 laptop configured as close as I can get to a 17" MacBook Pro.
Remember, MacBook Pro's have had 3x3 antennas since the last refresh (February). Be sure to pick Windows 7 Ultimate, too, so that you can get whole disk encryption (you know, that thing that's built in on Lion?).
Of course, you also have to make sure that you pick the high-resolution screen (which, for the record, still isn't as high-res as a 17" MacBook Pro screen). Finally, don't forget to get your 15 month subscription to McAfee to protect your data from viruses and malware.
Now, let's compare that to a 17" MacBook Pro:
Oh. Well. Hmm. I see a difference of $120 (that's including the $50 upgrade to the anti-glare display that I did on the 17" MacBook Pro). And you have to run Windows to save that $120. By year 3 of owning your laptop, you'll have paid more than that in Antivirus fees.
Also, that laptop weighs 9 1/2 pounds. The 17" MacBook Pro is 6.5. Furthermore, your brick of an Alienware laptop only manages 3 1/2 hours of battery life while browsing the web via WiFi. The MacBook Pro gets 7.
So...did I win the game?
TL;DR --> Alienware troll got owned.
