Upload PDF Files to Google Docs
Update: In less than a day, the feature has been added and you can now upload PDF files, share them and view them online. The PDF viewer is not very advanced, but you can use it to search inside a PDF file, select a block of text (Ctrl C to copy the text) and go to a certain page.
PDF is a great technology, but Adobe Acrobat (the program typically used to view PDFs) is awful. One of the things I miss most about linux is konquerer, the non-Acrobat PDF viewer. Now I have a way on Windows to easily view PDFs withoutAcrobat: Google!
