However, during travelling, especially when it is only for a few hours, one does not even feel like editing any text (except for small corrections). It is a good time to read books/papers and listen to music. I use olivepad, which is the Indian version to the Ipad and costs around Rs. 15,000. The advantage of olivepad is that it is touch screen, weighs less than 400 g and switches on instantly. It is directly synchronized to Gmail, Google calendar, Google tasks and Google docs. It runs on my favorite system, Android and has a number of free applications, including a heart rate monitor. I list below the applications that I have installed and often use.
The olivepad comes loaded with the software, "Documents to Go", which can read Doc,xls,ppt and pdf but can not edit any of these documents. You need to pay for the premium version if you need to edit the documents. OliveOfficePremium can view to view and edit Microsoft Word(doc/docx), Excel(xls/xlsx) and PowerPoint(ppt/pptx) files. In addition, it can view pdf and chm files. There are several instances where you just need a good editor for simple text. One of the best software for this is the Jota Text Editor.
Considering the large number of books available in the epub and pdf format, the best epub and pdf readers are Aldiko book reader and APV PDF viewer. The former (effective version 2.0) can read PDF but the APV PDF viewer is much better.
The android system was designed to manage its own memory and the concept of closing/exiting an app does not exist because the operating systems manages the memory and apps ensuring that the apps that run in the background do not use much resources. However, one needs to know which apps are running, memory used etc. This can be done by the software called ZDBox.
The olivepad comes with a browser but it is not as good as the Opera Mini browser in terms of speed and functionality. The olivepad also comes with a music player but it can not play some formats (like flv) and the moboplayer is probably the best software for playing videos. I used to be a state chess player and I found the software Chess Free to be quite good, though it is adware.
Please let me know if you have any favorite Android apps, especially for reading, viewing/listening to media and browsing.
