Glad to hear it!
I'm especially glad to hear you were able to get it so quickly after hearing of other's problems with the retailer I was initially recommending.
The RAPID tech only works in BootCamp, so far as I know. I do have my Samsung split in equal halves between OS X and BC because I occasionally use Windows for gaming.
However, there is another advantage to having BC. You mentioned your Samsung firmware is up to date but mine wasn't when I got it. Upgrading firmware from the Samsung Magician is a pleasure. It takes about 20 seconds and couldn't be easier.
Upgrading the firmware using the Samsung boot images on optical media or thumb drives, on the other hand, is a nightmare. In my case, it just didn't work. For others, I've heard even worse where it says "flashing" and then just stops dead.
If you have a copy of Windows, I really recommend installing at least a small BC partition somewhere, if only for running Magician,
NOW, if Samsung could finally release an OS X version of the Magician software, that advice might change.
