How do I get Keynote from Mac to a Dell?

Question

After intending to for over a year and actually working on a Keynote presentation for many months, I finally finished the project last week. My intent has been that when I'm done that I'd convert to Power Point and display all my work on a Dell PC in the building.
I did the conversion thing as per instructions in the Keynote manual. I received a message that conversion was complete but there were a few errors. Ok, I thought, I'd read that it doesn't convert perfectly.
Now what? I figured putting the Power Point file on a 128 MB jump drive would be an easy way to get the presentation to the Dell that is hooked up to the Power Point projector. I did just that and gave it to a PC person. He could not even get the jump drive to show up on his desk top or my file. He tried 2 different Dells - same thing. I've been trying to figure out that problem.
I tried emailing him the file but was told the file exceeded file size. File size is 2.5 mb in Keynote. It inflates to 6.5 mb when converted to PP!
Meanwhile, I accidentally opened the P.P. file on my Mac. What a mess! My beautiful presentation sure isn't what I made it to be. Changes of colors to make text unreadable, change of shapes of text boxes so they don't fit in shapes I created them in anymore. Is all this normal?
If so, I'm not sure it is worth the effort to convert to Power Point!! IF I can somehow get the Power Point version on one of the Dells, will I be able to clean up the mess on a PC that has the Power Point software. Is it worth the effort?
Should I just consider physically picking up my chunky older iMac (at least it has a handle on top unlike my newer eMac!) and carrying it into the room where the PP projector is?
Can I assume that whatever it takes to hook up the Dells to Power Point stuff can also be hooked up to my iMac? ie shove the Dell aside and put the Mac in it's place. I know nothing about what it takes to hook up PP to a computer.
Help! Keep me "crying" a lot from all my many lost hours of work to create my presentation.
Thanks for your help.

Does not look easy.
You seem to have a slot loading, CD-RW iMac from 2001 (500-700 MHz).
Your eMac is more promising:

It has a mini-VGA output port.
I'd take the eMac (get the VGA display adapter to connect) or ask around, if anyone lets you use his/her iBook or PowerBook to present. Much easier than mess with your presentation on a PC (and you know the Mac
If you manage to get the presentation right in PowerPoint on the Mac, you could burn a CD to transport the file to the PC. This usually works without any problem. (If the PC does not recognize the memory stick, it could be it runs on an old version of Windows, and needs to have USB drivers installed for the memory sticks.)
Hope this helps

PS: If all else fails, to mail to the other person: divide the file (part of the slides, only slides with pictures matter) into chunks that are smaller than 2MB after conversion to PP - burning a CD is much faster.
