Of course the best PDF reader for your mobile device (I am talking now only about the Android devices, although Apple iPhones and iPad can also use it) is Adobe Reader created by Adobe Systems. The application is free and it has been the released for Amazon on June 24, 2011. Another PDF reader, only that this time a paid application is ezPDF Reader developed by Unidocs Inc. Probably the beginning of the name of the application wants to suggest that this is an easy to use application.
Aldiko Book Reader designed by Aldiko Limited and released on Amazon on March 22, 2011 is another great app. I am a little bit surprised to see that Adobe Reader benefits of only 3 stars while the second app named by myself in this article, which has a price of $1.99, because I haven't mentioned the price, benefits of 4 stars. Nevertheless, I will start my presentation with Adobe Reader; usually when you read a PDF file on your computer, you don't experience the kind of problems that you can experience while you are using a mobile device. For example, the viewing quality may not be equaled by a computer, which has the best resolution ever for a PDF file. Well, what Adobe did with their apps was to re-create the resolution that is capable from your computer to your mobile device, without actually creating the hardware parts.
What they have done was to transfer a PDF file and a very good resolution on a small screen. You can see the PDF files as they really are, which is amazing. Of course, there is a Search function and you can move to what ever part of the text you want simply by using certain keywords or key phrases in that PDF file. This application can be moved to your SD card, as long as you don't want to occupy the place in your mobile device with another application. Although I would not do this, because this is the kind of app that you want to have always in your device.
You don't know when your boss decides to send you a document having the PDF format; you must be always ready to be capable of reading it. If you will not read it or perhaps if you decide to read it from your computer, your boss could think that you are not effective and this could have negative consequences for you. This Adobe Reader program and the rest of them that were named here are great for professionals and for students.
