I might take this box as well, available for my city since launch but i am afraid of Airtel's terrible buggy selfcare and app. Infact today i got trouble checking data usage and chasing twitter airtel presence but dumbos unable to understand and asking for screenshots again and again. Then sending USSD codes where as web based check i want which is stuck.
I am also waiting to hear about Tata Sky android box. I can upgrade my existing connection without ditching current hardware. If it doesn't happen for long i may look for alternative android boxes.
