Adobe reader can be used to open PDF files which are created with Adobe Acrobat. Recently I installed a newer version of Adobe Reader on my linux machine. It is working very good. You can easily view, print and search PDF files using the application. You can also create Inteeligent documents with Adobe Acrobat 7.0 Professional. It can be used to extend commenting capabilities for e-mail-based document reviews. So taotally I like adobe reader very much.
