I want to buy a laptop in India. The price range must be somewhere between RS 15000 to 20000. Please suggest me a laptop which I can buy. Thank you.
The configuration of the laptop must match your way of using it and for which purpose, Should be DirectX11 compatible to host Windows 8 if you have in mind upgrade to Windows 8, if not DirectX10, but for the coming new games DirectX11 is important.
The price range that you specify will get you plenty of 'netbooks' and 'mini-laptops'. These have really small screens (~10"), are more light and portable (than the conventional 14"-15" laptops that we are used to seeing around) and run on the Intel Atom processors (which result in better battery life, but lack the processing power that conventional laptops have).
However, I found you this : http://www.flipkart.com/computers/laptops/toshiba/itmd3ngpzrz8acjy?pid=comd3h3uxh2xkzme&_l=n0F_2X6gct0sx4lfOqXOzg--&_r=NjmVgSXdgC7ssJxLvP5AWA--&ref=0c2afa07-cf8b-4071-b815-65b5d6077776
This, in my opinion is the most value-for-money lappy currently in the market.

If you want a very portable machine for light usage, here's a list of netbooks for the price range that you specified: http://www.laptoppricelist.in/laptops-from-rs15000-rs20000.html
Do keep in mind though that laptops are bulkier, larger and more powerful than netbooks - which is why you should buy a laptop if you are looking for a machine that will get your work done faster.
Compare and buy a product that suits your specifications and needs properly. :)
