You have to assess your needs and look for the particular configurations.
Basic idea is look for high clock rate processor with like core i3/i5/i7, min 4GB RAM, good graphics card, nice bus speed, HD screen, wireless g/n support, some USB ports, HDMI slot, memory card reader slot, DVD player or better blu-ray player.
I recently bought
Toshiba Portege R705-P35, it has all the above except blu-ray player. And also some extras like 4G Wimax support, Intel WiDi (Wireless Display direct to my TV) and it is just
3 lbs in weight
I paid USD699.99, which is approximately 31,500. So you should get it under 40K in India.
Or pay around 45K and get Sony Vaio with same or higher configuration.
