Hi, everyone. I'm new to MacRumor and Mac itself. I've never had Apple computer, but I've been looking for a new laptop for college (i'll be a first-year engineering student this august) and Mac seems the way to go. I've decided to get a MBP I'm just not sure what specs I should get. Even though i'm on a budget, i'm willing to spend extra on something if it's really worth it. Here's what I'm debating over: -15 inch 2.2 or 2.4 ghz -160GB HDD 5400 rpm vs. 7200 rpm The 2.4 ghz will be $434 extra since I'm going with a 160GB HDD. Is the .2 ghz extra worth the extra cost? Compared to the 160GB 5400 rpm, the 160GB 7200 rpm is an extra $135. Is that extra cost worth it too? This laptop will have to last me for my next four years of school. I'll be using it to run engineering programs such as MATLAB, listening and downloading music, watching movies, e-mailing and IMing, browsing the internet, word processing, etc. What I won't be doing is playing video games. Nor will I be doing any intense video or photo editing. i'll also probably be installing windows on it eventually and either use parallels or bootcamp as many engineering programs only work in windows. any recommendations on parallels vs. bootcamp? Thanks guys. I appreciate all the help. If you need me to give you any more info, I'll be more than happy to share it.
