Go with .in extension, .asia is a bit more wider context and so looks off-track. unlike .eu for europe, .asia is not worthy, because europe is more of a single entity with europian Union present. This is not a case with asia, and each country is segregated.
I'd avoid .co.in domains, as they're not usefull for simple users. Also, if the majority of the business is in India, then I'd go with a .in instead of a .asia one.
For my opinion, i will suggest "co.in" if you are targeted the Indian market because it's easy to be memories for the Indian market. For ".asia", i didn't suggest it because this domain is "confusing" the visitor due to the unknown location of the webpage.
I agree with everybody else, I think .in would be the best choice. It is easier to type in than .asia and it also can stand for many different things. I bet a lot of people would not even realize that it stands for india. That's just my opinion. However, if you're website becomes popular enough, I don't think it would really matter which one you use!
Re: .asia or .in? Which one to prefer?
