Kapil Sibal's not resting after the explosion of interest that followed the initial launch of the $60 Aakash education tablet. He's now pushing to get the rebadged DataWind Ubislate 7 into the hands of students free of charge, rather than the $35 they currently pay. The plan is to offer a 50 percent government subsidy for each unit, with education institutions fronting the other half, but only if inclined to do so. He's also pushing for the tablet to be manufactured domestically rather than imported -- hoping that the comforts of home will enable it to spread nationwide. See? We got through that without making any "cash" puns.
