Any thoughts?

[redbeargrl]

If anybody has any experience with either writing package Scrivner or Story Mill, I would dearly love to hear your comments on their usefulness, ease of use or any other thoughts you might have.  Or, if you have any input on other writing packages, that would be lovely as well.
Also, do any of you publish your own works as eBooks?  Any thoughts on Smashwords or similar sites?
Obviously I'm floundering here...
