The official site for Ubislate – the commercial version of Aakash tablet has put up another form, now for Pre-booking the Ubislate for purchase. Earlier I had posted about the Enquiry form. You can prebook at http://www.ubislate.com/prebook.html
This is the official site http://www.akashtablet.com/
So once you pre-book it, they will email your booking ID for you.
