So I have several choices which may confuse you. Basically I have the 2.2 Ghz SR MBP with the 120 gb hardrive which is much to small for me. I like to have a large collection of music and movies with me as well as my windows partition for gaming. I have 3 choices 1. Amazon.com for a 320gb passport drive which i can switch out with my 120 gb and have an extra 120 gb external drive to use for 179.99 free shipping 2.Craigslist.com i found a 250 gb passport drive for 120 flat 3. Wait for the new spinpoint m6 samsung 500 gb notebook drive coming out in march and buy it for what is probably going to be in the high 200's I'm really tempted to wait but money is also an issue. I don't want to spend a whole pant load of cash as I'm a student. That being said, 500 gb in a notebook drive is very very tempting.
