I dropped an OCZ Vertex in My MBP Unibody this week and it's been amazing. I posted up some thoughts and findings: http://blog.iso50.com/?p=9841
What I didn't mention in there is that I can now run 2 extra decks in VDMX with no noticeable lag (I used to get lag with just my normal 3 deck project). Next step is to get another SSD and replace the normal drive in my eSATA external.
