I might also add that the 45 gig drive is a real plus IF you have outside storage such as a Zip drive for the goods. If you haven't safety-stashed your data at in at least two other places, WHEN it blows, you're going to emit a scream audible in Vancouver.
And while I'm no stranger to hunger for new patches, don't overlook the inevitably excellent starting points Korg provides. I was able to get a couple of jewel-rattling Moog-y basses with very little effort, just by doing some noodly programming for a couple of hours. In many cases, those "vintage" sounds are closer to the surface than you think, so that card could partially be seen as a luxury rather than a real need. Just FYI.
