A standard format is needed for document sharing. PDF is the option with no alternate because Microsoft Office is expensive one (US $ 165) to an extent to mass community. Where PDF is free and every can use it.
But does it really free? How you can make a pdf document with the acrobat readers? For creating a one, you need Adobe acrobat writer/professional edition. Latest edition costs US $299 :D. Yah you can download many free software from the web to convert your document to pdf format. You can also download freeware to read your office doc. What’s the point of discussion then? Right you are :) with that freeware you can only view your doc; no editing or saving option. So you have to buy the software to make a word doc. That's why PDF is the best option for information transmission. Another important information, word doc can contain the macro virus :P
More latest versions are available on Adobe Acrobat site but they are too heavy in size. So, here I give you a stand-alone link to download Adobe Acrobat Reader 7.08.
