But presenting a slideshow doesn't have to mean using PowerPoint. There are a number of totally capable open source alternatives to PowerPoint for giving visual presentations. In many cases, the features of these “alternatives” are so compelling that, unless you're absolutely forced to use PowerPoint, I don't know why you still would.
I've got a few new presentations to give coming up in the next couple of months that are essentially being developed from scratch, I thought it would be a great time to take a look at all of the open source presentation tools out there, and decide if it would be a good time to try out a new tool for any of these upcoming talks.
It's also worth taking a little time to ask yourself what assumptions you are making about your presentation needs, and what kind of tool makes the most sense to use.
