Till today I have never been able to spread Ubuntu among my friends successfully.(I live in Bangalore and all my friends are Bangaloreans and Bangalore is known as the IT Capital of India.)Even though I installed Ubuntu for all my friends none of them actually used Ubuntu for more than a week.Some of them removed Ubuntu and flatly refused to use it again in future.Some of them used it occasionally to download stuff from torrents and to clean infected USB Drives.Based on their feedback ,I figured out why people(especially of India) are not too keen on using Ubuntu even if it is installed on their computers.
