You wanted to be able to produce those pro presentations with PowerPoint. But Microsoft Office seemed to expensive to buy it, so you decided to download an illegal (but free) version. No! Hold your horses. Real solutions are appearing all over the place.
Up to now, you had the possibility to use Open Office (which just went to version 2.3). This free desktop suite is compatible with Microsoft file formats (Word, Excel, PowerPoint) and gives you the ability to do nearly everything that PowerPoint does. And -we have to admit that- we do not use a lot from PowerPoint (bullet lists and titles).
But Google joins the race with the arrival of Google Presentations, which their online answer and free again (and more legal than any botleg copy downloaded from BitTorrent, DirectConnect or similar P2P network). There was already a Google Docs application suite; It is now complete.
Have fun with your free download of… PowerPoint competition products.
