There are lots of netbooks available in the Indian market with a price that is below 15k. Netbooks with Intel Atom processor have a starting price of Rs. 10,000. Make a decision based on your requirements like the storage space, weight, batter life, RAM etc. Along with it also look at the brand name and the after sales service.
I am using an Intel Atom based netbook since last year and I am very satisfied with its performance.
