I really appreciate everyone's thoughtful input as this field of interest is relatively new to me. I had some personal preferences but I didn't want to specify in order to hear from others their own.
There is going to be the need for RTL languages, with Hebrew initially.
I currently own Mellel and it seems fine, although the interface is indeed "idiosyncratic". One other thing I disliked was mellel's proprietary file extension. I may be thinking wrongly about this, but why not have a general text doc file format such as rtf, or doc? If I need to open the file on another persons computer for a quick error correction, how likely is it that they will also have Mellel? I will look into Nisus Writer Pro.
Pages and iWork in general interest me for the more general tasks and I like the idea of using Keynote as opposed to Powerpoint to layout presentations for teaching. Although I wish Apple's education pricing was more aggressively discounted.
As for the Office suite, it's advantages are that it's heavily discounted and more widely used, the latter minimizing concerns of compatibility. However, I'm holding out to see if a new iWork is in the works for a possible summer release.
For the present time, the majority of my work will be on a Macbook Pro so it appears that both Sente and Bookends are fine.
Edit: I wanted to note that for PDF's I have Acrobat Pro as part of the graphics suite. I can't think of anything I can't do to a PDF that Acrobat does not do.
Again, I really appreciate the input and still welcome more discussion!
