Sorry for the misleading title, officially it is not available i have asked the seller about the warranty incase the device is DOA.It is US import and will be delivered after 10 days (may be more) and probably will have no warranty (unless Google or whatever the company is does provide international warranty).
Officially still not available right ?
Asus offers global warranty and you can approach nearest asus service center in india for service once the product launches officially in india in coming months. We can provide you a copy of original purchase bill.
