Apple Keynote design
Keynote began its life as the private presentation tool of Steve Jobs. It has since been released as part of the iWork suite, and has much of the same capability as Microsoft Powerpoint. The key difference lies in the level of on-screen visual refinement and elegance. With Keynote, typography is smooth and crisp, video importing and playback is more reliable, and transitions and animations simply give you more Wow-factor. It's also a very affordable piece of software - coming in at around twenty euros. This all sounds great, however its major downside is that (whilst you can export approximate Powerpoint files from Keynote) the software itself is only available on Apple devices and it is not available on Windows or other operating systems. But if you want visually slick and elegant slides, Keynote is the recommended option.
