Its failure of Indian intellect to introduce Unicode (in computers) and sufficient infrastructure & training for Indian population to write in devnagri script. When you see browser and operating system supporting 20-30 languages including chinese and right to left aranbic script as standard where as none of indian languages are included into it.
Its shame that our intellect population proud to be english speaking think themselves as superior over rest of population and never care to introduce equal opportunity.
Thanks to their (including me) in capability, my father (who is literate and better mathematician than me) cannot use computer and cannot send emails in Marathi langauge.
It simply puts off most of population (which is currently living in villages and over 40 yrs) in India.
No wonder PC penetration only remained within young generation.
Hindi and all other languages of world can be/should be writtig using the original Devanagari script, which is more simpler than Roman (English), straight, single tire, Speech to text and Text to speech compatible.
Your tests are at best anecdotal so please pass them off as sometihng really useful. The point for not using the Hindi characters is lack of proper User Interfaces for Hindi... since these are designed by NON INDIANS for Indian languages. So just shut the crap!
The opportunity to provide a uniform script to all Indian languages was lost way back at Independence time. The need of the hour is nurturing of Indian languages among Indians, and this could have been done a little more easily if all Indian languages switched to the Devanagri script. After all, most Indian languages use the Devanagri in some modified form. Bengali for example had its type designed by Englishmen from the Devanagri. Romanization of Indian languages may be a good idea, provided it is done for all languages and a similar phonetic form is adopted. But then you are throwing away a script form of thousands of years. Very soon India will assume its rightful place as an economic superpower, and it cannot do so unless it asserts its culture as well. I say stick with the Devanagri and expand it all Indian langauges.
It is a great idea whose time has come. We should perhaps use the Roman and Devanagari scripts for ALL the Indian languages. With the growing mobility of the Indian populace across various States, the number of 'educated' Indians who are illiterate in their mother tongue is already significant and growing. The standardisation of scripts is the crying need of the hour.
