Sorry for my ignorance, this is a newbie question:
I am trying to migrate from Mac OS X to a Linux distribution, maybe/probably Ubuntu. One of my favorite applications for the Mac was Apple Keynote, which makes amazing sideshow presentations.
Is there an equivalent solution for Linux distributions that matches/comes close to Keynote in terms of its polish and ease of use? I know about OpenOffice.org Impress but, no pun intended, I am not very Impress-ed...
