So, doing a little research on my next purchase and it seems that a user can put an SSD as well as a 16gb in the MBP themselves. This comes in at a cost of around the same as the new iMac, with 16gb and Fusion Drive based on a few estimates I've done. Although we'll find full costs out for sure at the end of the week. Has anybody any thoughts on which of these solutions would work best in terms of long term usage? By adding the SSD and RAM to the Macbook, or would that machine perform differently to something made BTO by Apple? I'm happy to look inside a machine to change a few pieces, but I've not heard much about how self upgraded laptops perform long term. And also by doing this, could you run 2 SSD drives in the MBP?
