I have purchased Dell Inspiron 15 3521 model Laptop one year back. The brand DELL itself is trust worthy.Having already installed windows 8 operating system.It is touchscreen model with fluent touch sensibility having 4 Gb RAM, 750 Gb Hard drive, 2 Gb Radeon graphics card with four USB ports along with one LAN port.
It cost me for 48000.Now price may have been fallen down. Since I am using this not a single problem has arised till now and working greatly. One of the best laptop in the market.
