I always disable in-camera sharpening entirely. The primary reason for that is that sharpening is an irreversible process; some image detail is always lost in the process of emphasising the edges in the photo. As such, if you're going to be doing software post-processing on your photo, you will probably want to keep as much of the original image detail as possible first, and then apply sharpening only right at the end after all your post-processing.
A second reason for foregoing in-camera sharpening is that there is no "one size fits all" sharpening formula that works in all situations; chances are that you will want to vary the sharpening parameters depending on the exact content of the photo. For instance, you'll want to bring out all the fine detail in landscape photos, whereas you probably don't want to emphasise every skin pore in close-up portrait shots.
Another consideration is what you intend to do with the photo in the end; generally speaking, photos intended for on-screen display shouldn't be sharpened as much as photos intended for printing. As such, you will generally want the flexibility of manual control and fine-tuning of the parameters for the sharpening algorithms, instead of letting the camera just apply the same formula to every photo.
The main disadvantage to disabling in-camera sharpening is, of course, the fact that you're going to have to process each individual photo yourself. Many of us already do that, but if you're more used to simply downloading the photos directly from the camera and keeping them without any further changes, then perhaps enabling in-camera sharpening may be better for you.
