Nope, still have my optical drive - no that I use it for much. I had a Seagate Momentus Hybrid drive that I took out for the Crucial. I've noticed a big difference in somethings: opening documents, programs (PS CS6, Lightroom, etc.). My boot times aren't much better because before they'd run on the SSD section of the Momentus that was there before.
I have read about the optical drive area replacement kits, just never went that route. I may consider it... I have to use an external for all my photos as they take up some serious space.. but a 256 GB SSD and a 320 GB Regular Drive would be okay for a while.
