Here's my review: http://jesse.kline.ca/blog/42-linux/155-ubuntu-1004-lucid-lynx-review

So... Neptune is kind of like a fat chick?

When saving my own documents for personal use, I always use the native OOo format. This is mainly because my experience with OOo's MS import-export feature has not been all that great (ie. bugs seems to pop up often). However, none of the people that I correspond with use OpenOffice, so I end up saving a copy of documents that I'm sending to people in MS format.
