I'll preface this by saying that it's a priority that I get a Mac for college. I've had a 13 inch white MacBook for about 3 years now and I will never go back to PC, period. I'm going to CSU to major in Computer Science and like many other students, I'm debating on getting either the 13" model (portability) or the 15" (performance). For some of my CompSci classes, it's pretty safe to assume that i'll have to run VMWare Fusion/Parallels to debug other OSes (Linux, Windows) and run apps like Python. What concerns me most is that the 13" model still sports the Intel Core 2 Duo chipset which is long outdated and Intel has already moved on. The 15" model would be more time-proof since it features the i5 chipset but it's also 2 inches larger. And yes, I've heard about the rumors of Apple announcing a new lineup of MBPs around April but it was also recently announced that Intel has recalled their Sandy Bridge chip architecture, which the new MBPs were supposedly going to utilize. I should also mention that this laptop will be my primary computer and most likely my only computer throughout my four years of college which really makes that i5 more appealing since it's newer tech than Core 2 Duo, but the portability is also a concern for me.
