PDFs are NOT similar to Word documents. People write stuff in other programs, then CONVERT the final result to PDF because PDF is a format designed to precisely lay out text and visual elements in a precise way so that it can always reproduce the original document exactly. And dude, PDFs are not small files, in fact it's a fairly large, 'coded' in human readable text with historically weak image compression algorithms. Ok that was a terrible definition of PDF.

I find myself sitting at the computer for along time just to get all the information in one newsletter! I save all of them so I can backtrack at a later date. This letter is better than reading all the computer books I have because you can get to what you want right away. Just wanted to let you know what a great job you are doing.

BTW, you don't need "full paid versions" (which cost hundreds of dollars) to create a PDF. Macintosh users can create PDFs with the Pages program, part of Apple's iWork suite ($79). PC users may use ABBYY PDF Transformer ($100) as well as other PDF-creation tools. See more about PDFs on the Ourmedia Learning Center: http://ourmedia.org/node/328718 Good piece.

Virtual printers are great - no standalone program to handle. Just print *anything* - select the PDF virtual printer in the printer list, and hey presto - a PDF. This freeware is easily found via a web seach :) For casual PDF writing, there are a number of free PDF virtual printers available on the internet.

It's "portable" because you can send it to anyone. 2) PDF file size is dependent on a number of factors; there are many instances in which PDF file size will be larger than the original format. For instance, if you take a low-quality JPG and save it as a high-quality PDF, the file size will increase. Or if you take a Word file (which doesn't include fonts) and convert it to a PDF-with-fonts, the file size will be larger. 3) PDFs don't necessarily include fonts. High-end apps give you the option to include or exclude fonts in PDFs. Especially with large archives of smallish files, excluding fonts can save a lot of disk space. 4) PDFs have the capability to contain vector (resolution-independent) graphics, but because (as you noted) they also have the capability to contain raster (pixel) images, it is not accurate to say that PDFs are by nature resolution-independent. 5) Mac users can create PDFs from any document in any application, including browsers. Choose "Print" from the "File" menu, then click on the "PDF" button in the lower-left, and choose "Save as PDF...". Slick, eh? A few corrections about PDFs, Chris:
