Powerpoint Bloat

[phiscock-g851W1bGYuGnS0EtXVNi6w at public.gmane.org]

I recently had occasion to move a presentation from Microsoft Powerpoint
format to Open Office Presentation format. Comparing two presentations of
roughly the same complexity, both containg jpg images and text, the
Powerpoint file, which was created using Microsoft Powerpoint is a full
*ten* times larger than the Presentation file: approximately 22 megs vs
2.5 megs.

When I save the file from Open Office Presentation in Powerpoint format,
it's approximately the same size as the Presentation file. My guess: the
original Powerpoint file uses one word per pixel and bit-maps the images.

There is a compression utility available in Powerpoint, and when used it
produced a zero-length file. Either it's incredibly effective at
compression ;) or it's defective.
