I hate powerpoint presentations. They're typically boring, information crowded and lack any real punch. I also have to use powerpoint as a regular part of my job in order to convey information in either pre-sales presentations or to communicate with the rest of the department or business.

I've just stumbled across the Beyond Bullets web site which has a number of useful tips, however the thing that blew me away was a link to a presentation about Identity 2.0 that shows how powerpoint can be used to it's maximum. Have a look at this link http://www.identity20.com/media/OSCON2005/ and be inspired.
