At last I got one. I got a simply configured laptop. Though today I went to IDB to purchase a old Fujitsu laptop, some well wishers requested not to buy. Then I have bought a HP laptop configured with celeron cpu.
Laptop was my long time dream. I have waited for it for about 2 years. Finally I got one. It was a quick buy. I will buy a Dell laptop at any later period.
I am grateful to the almighty as my dream came to true at last.
