I will expand a bit on Vulture's response.
I am a huge PDF convert. I began using it about 4 years ago when somehow I got a full version of Acrobat at work.
I typically have to write and send large contracts to clients as part of my work. When you absolutely HAVE to make sure there are no changes made to it, but you still want to be able to colaborate on it and get someone's feedback on what needs to change, PDF is the only way to go. The permissions can be set in many different ways to allow just printing, no printing, changing the doc, annotating (or not) highlighting and a myriad of other things.
In addition, the presentation of the document you are working on will always stay the same. When I began my own company, I did EVERYTHING. I started off using MS Publsiher to design my brochures. When I sent the publisher file to my printer, I got it back with all the margins messed up. Why? he had a different version of publisher. I should have sent it in PDF. In PDF, it is always the same across platforms, Operating systems and versions. This is because the thing you look at on the screen is created from the Printer instructions which do not change.
When I signed contracts for my own company, I did so digitally. I never had to have a paper contract and so I did not have to wait a day for FEDEX to get there. I could conduct business transactions the same day with a digitally signed contract.
I also like the ability to take a form and fill it out on screen and print it out, rather than have to print it out and fill it out with a pen. It looks much cleaner.
There is a lot you can do with the File type, but most of it can only be done with the full version of Acrobat. It is expensive, but at least in business, it is very valuable.
BTW, I know you were complaining about the file sizes. Typically the file sizes are MUCH smaller than any Word doc of Powerpoint files. The whole thing is designed to be very compact. PDF is supposed to stand for Portable Document Format. They should not be crushing your system resources. . . or at least should be the last thing killing your comp. Is the computer otherwise crappy or is this just a PDF thing?
