Creating an interesting, informative, and elegant presentation or slideshow for a company meeting or job interview doesn't have to be difficult, and you don't have to lock yourself into Microsoft PowerPoint to make a good one, even though it's the industry standard. Earlier in the week, we asked you which presentation tools you preferred. You responded, and we took a look at the top five PowerPoint alternatives. Now we're back to highlight the winner.
Voting was tight all weekend, but even though it's Mac-only, Apple's Keynote edged out the competition for the top spot with just over 35% of the votes cast. Behind it in second place however was the web-based Prezi, with 26% of the vote, and in third place was OpenOffice.org and LibreOffice Impress with 18%. Hot on Impress' heels in fourth place with close to 15% of the vote was Google Docs, and bringing up the rear in fifth with close to 7% of the overall vote was Beamer.
