"Don't forget it's a 2.5'' drive, those are more expensive... I don't think "many times more" is true, I doubt it's even twice as expensive as other 120GB 2.5'' drives."
Yes, 2.5" hard drives are more expensive than 3.5" hard drives, but $180 for the 120gig hard drive is still VERY high. You can go to http://newegg.com and pick up a 160gig 2.5" hard drive for around $90-100. Microsoft tried to justify the price of their hard drives by saying a bunch of things but personally, I think the 20gig and 120gig hard drive prices are just a ripoff. The 2.5" 360 hard drive being more expensive looks even worse when you compare it to the PS3 being able to use pretty much any 2.5" hard drive as opposed to the 360.
Also, be forewarned that if he does get the 120 hard drive and orders that cable to transfer the data, it will copy all the data from the 20gig hard drive to the 120gig hard drive, but then erase everything from the 20gig hard drive after once it's finished.
Anyway, back onto the topic at hand. You'll be getting the 20gig hard drive for free when they normally cost $100, that's a good deal.
