But I think still 60% use Bijoy and bijoy is familiar to 60% Normal Computer user and Avro is also not a good software i think i use UniJoy of ekushey and as far i think this 1 is the best because you don't have to use any EXTRA software for that which is much more preferable.
How ever i also have Bijoy 2003 and himi2008 maybe you won’t able to download Bijoy 2007 cuz it takes almost 2500 bucks i think. Everyone still use 2003.
