Yeah, since refurbs are so reliable, and I plan to get the 3 year warranty anyways, I will probably go for the refurb if it's available in the build I want. though $100 is a small fraction of the price, it's still $100.
I know I want a 15", and I know I want a non-glossy screen. If that configuration's available, then I'm set. However, there could be other factors too. For example, when I bought my 15" 2.16ghz macbook pro back in march, I also wanted Final cut express and at the student discount, it was $99 extra. Had I not bought the macbook pro as a student (it wasn't available on the day I bought it so I didnt have a choice anyways), I believe it would have cost me an extra $200 so the savings were gone right there.
this time around though, I'm not sure if I need anything extra with what I'm getting.
The big question is just what 15" to get - the 2.2ghz or the 2.4 ghz. It's a $500 price difference. My plan is to max out RAM for sure. Is there any other reason to get the $500 more expensive option?
