RMA stands for "Return Merchandise Authorisation", if I am not mistaken. Meaning you can return the merchandise to the retailer. Depending on what is the retailer's policy, you can either return it in exchange for a new one or in exchange for a refund. The retailer for the Nexus 7 in your case is Google and it appears that they have a policy of allowing the return of the device in exchange for a replacement unit. I don't know whether they do full refunds.

The point is, the retailer is Google and not Asus. And the RMA policy is Google's, and not Asus', a very important distinction. The guy at the Asus SC told me that normally, for Asus Malaysia's merchandise, they allow 1 to 1 exchanges under warranty PROVIDED you go back to the authorised retailer you bought it from within 7 days and the authorised retailer should exchange it for you. This is Asus' (at least Asus Malaysia's) RMA policy. However, this doesn't apply to the Nexus 7 as it is not officially sold here. In any event, how are you going to return it to the retailer if it is the USA?

This is where Google's RMA comes in. AFAIK, Google's RMA is even better. It is good so long as you lodge in a claim within 15 days, and they do a 1 to 1 exchange for you under their RMA. But do you want to go through the hassle of the RMA process when you are here and Google is in the US?

There is no reason at all why Asus should handle Google's RMA process for Google, unless Asus is obliged under some contract, which I doubt. Asus' obligation is only to do repairs, failing which, then only do a 1 to 1 exchange. If I am not mistaken, they must attempt to remedy the problem without the exchange first.

And can you really blame Asus Malaysia for not knowing when the spare parts will come and what is the turn around time for a repair? It is not sold here officially. In fact it is only sold officially in 5 or 6 countries. Professional and efficient support will be difficult if it is not officially sold here. On top of that, this device is so new! We only hope that Asus Malaysia tries their best.

This is the risk one takes when buying something from overseas that is not officially sold here. I knew the risk, and I took it. At least, it is covered by international warranty and I don't have to pay for any repairs or parts. And at least, Asus Malaysia honours the international warranty and accepted my claim. I can only hope that they will genuinely and sincerely try to solve my problems with the device. Remember, Asus didn't sell it, Google did. Asus only OEM'd for Google.
