The fact that you need one now, no. The deal is pretty standard right now at the $599 price point for a T6600. You are getting a larger harddrive at 500 gigs over many laptops in that range at 320gig but really, with the cheap prices of externals, HDD space is just a luxury
And Judge, I have to disagree with you regarding a 7200 HDD using up 40-50% more power. That is completely not the case and is complete bullshit. At most a 7200 HDD would cut your battery life by a few minutes over a 5400. Laptops use 5400 as its just been a typical 'standard'. They're also cheaper hence the decent pricepoint.
