Verdict: In a country like, India where broadband penetration is so less, and thus wi-fi networks stay out of question. Such a gadget won`t be of any use for the normal junta, except for a few rich geeks, I mean yes the T-Shirt is worth 1200 INR. Thats high, plus the 120 INR for the battery pack, and add to it the shipping charges and the taxes levied. Gosh, It will cross 2500 bucks Indian!!!.
