The beauty of the USB key is obvious - presenters can make last minute changes and bring their presentation to a host computer last minute (but, with virtually no time to check it out to make sure it works).PROBLEM
Here is a situation from an event in September, 2011 where a PC-based PowerPoint show was created as a .pptx and handed in to the host computer the morning of the event with no time to check it out. The host computer was a Mac with an older version of PowerPoint that only reads .ppt (not .pptx).
The slide show was too big to email and there was not time to FTP. The slide show was eventually transferred to another computer, which could save it in various formats, but ten minutes had passed (the error was discovered during the preceding presentation).

One might suggest that a presenter call ahead to ask what computer and software is being used, but there is no guarantee that the same equipment will actually be in place on the day of the event. A better solution is to have a plan B as well as a plan C.
SOLUTION
Save the slide show as .pptx, .ppt and .pdf, and put them on the same USB key. If the slide show has audio or video in it, the .ppt will still play the media, but the .pdf will not (unless something has changed recently that I am not aware of).
Another note about Macs - bitmaps need to be converted by Quicktime or else they won't show, so only use jpeg images (you'll still go through the 'converting metafile' process on the Mac, though, so allow a few seconds for the Mac to prepare the images for display).
