I like ellipses, I find them much more natural than the em dash which seems to be prevalent in modern fiction. (Though they probably have different uses, in practice they seem to be used interchangeably.)

If ellipses are representative of text omitted, then it makes sense for them to have a space before and after. I've seen the rule for a period followed by ellipses at the end of the sentence, but it (a) just looks wrong and (b) if the sentence just trails off, as denoted by the ellipses, then it's lacking a proper ending and a period seems wrong, like ending a question with both a period and a question mark, or an exclamation with both a period and an exclamation mark.

When it comes to ebooks, I'm always pleased to see when the author (or publisher) uses & hellip;. Ellipses breaking across lines is distracting.
