I'm a longtime PC user and I think I've finally decided to get a Mac (I'm most likely going to install Windows XP as a second OS though, just so I'm covered in the event that I need to run something in Windows). Anyway, I pretty much have it narrowed down to a Macbook Pro because I need the 15" screen vs. the 13" screen on the Macbook (this will serve as my main computer and I need it to be a laptop). I'm just a little confused as to whether or not it's worth it to pay the extra money ($400+) for the 2.4GHz processor vs. the 2.2GHz. I gather that the graphics card is better with the 2.4GHz processor but if I'm not playing games or doing any heavy video editing, does that really matter? For simple every day use (web browsing, email, listening to music, watching videos, etc.) will I notice any real difference with the slower processor? Looking at the comparison chart on Apple's site, I don't see any other differences. Also, I'll probably upgrade the HD to the 160GB version since it's just an additional $69 but I think that's about it on the upgrades. I don't think it's worth paying over $200 to go up to the 250GB drive since I could probably do that cheaper on my own and the 4GB RAM option is way too expensive. I do get a federal gov't discount so I'm thinking that I won't be able to get a cheaper price than apple.com (plus I can get some Continental OnePass miles in the process). Does this all sound reasonable? I'm so hesitant to pull the trigger because this is a completely new world to me and I want to make sure that I don't have buyer's remorse the second I click the "Buy" button. I also want to make sure I don't buy something that's already outdated and that may have me second-guessing my choice to go with a Mac. Thanks in advance for any help!
