Gmail allows you to type in Tamil
Long time back Google has introduced transliteration (NOT translation) for five indian languages including Tamil and Hindi. Later they integrated this feature to many of their products such as Blogger, Orkut, iGoogle etc.
Advantage of transliteration is you don’t have to learn any keyboard layout. If you type “namaste” transliterate service will transliterate this to “नमस्ते.” Similarly, “vanakkam” in Tamil will become “வணக்கம்.”
Though it’s a wonderful feature if you continue to use this you’ll get addicted to this service and will not be able to continue with normal typing layout. Therefore use is when there is no other way to type in Tamil.
Now Google has integrated Transliteration in Gmail too. It’s so good that we can directly type in Tamil, especially when we are in Net café or office.
