I am curious about this too. I want to get the 128 SSD, so I have room for growth and my parallels VM. And also enough space for documents, libraries, etc. via a secondary HD. If my apps are on the SSD and docs on the HD, will I lose speed?
I too am very curious about this. If you install the OS on the SSD as well as applications like iphoto and itunes, and then set the homefolder for the library in the HDD, will the applications still open up with quick speed?
