even though you made your decision ... here my 2 cent:
I would buy a bundle - meaning separate files for separate books - I would not by an omnibus - meaning one file with all those books - just to much hassle to get them into a library .... I do not like omnibus editions in pbooks, I do not like them in ebooks ...
and one question @ neilmarr:
do you ever update your books - for example because of mistakes pointed out after the first release?
because if you do, do not forget that now you have to update the omnibus, too ...
