So next week, I'll finally be able to afford my first MacBook (my first Mac ever). I was thinking of getting the 2.4ghz, simply for the backlit keyboard and the fractionally higher specs, seeing as I have the money for it. Though without realising it, last night I was typing on my current laptop in the dark without any trouble at all, which has made me wonder whether I really need a backlit keyboard... so now I'm also considering the 2.0ghz, because people have said the performance is pretty much the same between the two models, and the only time you'll notice the difference is when rendering, encoding etc, plus I can just upgrade the hard drive if I find myself needing more than 160GB. I'm still considering the 2.4ghz however, and just wanted to know if hardware wise, the 2.4 has any bad points when compared to the 2.0? Does the 2.4 get hotter than the 2.0, for example? Thanks guys.
