Actually I would have recommended a bookeen since it has the most extensive support for non-english langege books. I would also recommend translate.google.com, a web site that speaks 58 different langueges among them is Indonesian and English, enter the web address of the web site and the languege to translate it to and it will show the web site in what ever languege you want. Its a good way to learn a foreign languege. Second also try
http://id.openoffice.org/ a free software suite that speaks indonesian. I have a pal who is learning to speak Chineese in high school so he downloaded and installed Open Office for Chineese which is now helping him with the languege since it will insist on proper grammer.
