I am using for 3 years but now i am sorry to say that after i have used harisree malayalam keyboard i am moved on. I would like to share what i found necessary. Harisree contains a better transliterator than his for fast typing and virtual keyboard with movable buttons for easy arranging of buttons as users wish for a better typing . Just search in sourceforge for harisree and even by looking at the screen shot the difference could be found. Just search for it u will like it i dont have time for this shit.
