Not being much of a fan of MicroSoft (or overblown PowerPoint presentations), I was however really impressed with the ease-of-use of such a basic Slide Presenter (based on MS Powerpoint) and it had the feel of a Mac interface. It was called 280 slides. Unfortunately it is now closed and nothing is quite the same again. (see below)

It was only a Beta test site - but it had a good strong following. It was fresh, fast and elegent. That is how the next 'FREEHAND' should be, as intuitive as it still is, (those lucky ones still using it). The new 'basic' online FreeHand basic version could be'free' (just like the old 280 (beta) slides was) whilst the full 'pro' FreeHand online application could be an annual 'Pro' subscription to keep that full compatibility with the (still essential) Illustrator ai. eps and pdf formats.
Since 280 slides closed - I have reverted back to making my slides again using FreeHand; first creating the Freehand style 'template' and then exporting them as multi page PDF. I then use some old tricks I picked up (from early Acrobat 3 Pro) to embed page transitions within the exported PDF slides. I play them back full screen (on a School OHP projector). It is still impressive and much better than using PowerPoint. You can also easily add video links with Acrobat Pro afterwards, (once you know how, its not that difficult).
You can make some impressive presentations this way.
