Based on an earlier post about whether to buy new or upgrade my 2008, I'm going to do the latter. I think the first thing I'm going to do is upgrade the boot drive to an internal SSD. I'm going to go for the 240GB OWC SSD. The question is should I get the 3G or the 6G? I realize I will only be able to utilize it as 3G with this mac. Getting the 6G might future proof it a tiny bit. I doubt it though. In three years the 240GB might be considered a tiny drive in terms of SSD. The cost difference it $120. Anyway, thoughts on this? Is there any other reasons I don't know about one way or the other?
