It's a tablet war but of a different kind. Human Resource Development Minister Kapil Sibal and Gujarat Chief Minister Narendra Modi are engaged in a bitter battle over Akaash, the low-cost tablet developed by Mr Sibal's ministry. A few weeks ago, Mr Modi had ridiculed Mr Sibal and had questioned if the low-cost tablet Aakash is all in aakash -up in the air! Keen to respond, Mr Sibal promised that he would send the latest version of the tablet to Mr Modi when he visits IIM Ahmedabad in September. Video courtesy: NDTV
