last time i got my warranty transferred to india( 3 months back), they asked for email id of the buying person on the form. no idea if things have changed now..
Last time i checked, Toshiba has a similar config here at 31.5, ie i5 sandy bridge, 4GB, 500 GB 5400 rpm, 15.6, some nvidia GPU 1GB and 1 yr local warranty. That price doesnt seem to be that attractive for a US lappy.
Dell warranty is only transferable if it has NBD or any premium warranty. The normal warranty available with the laptop when you buy it from a store is non-transferable to India.
