Lenovo Thinkspad T430 is the best laptop.I am using this laptop T430. Its very user friendly and I am using for my official purpose. It have a 4gb Ram which is enough and more for the user but battery backup is very poor.It have 500GB hard disk and 4GB Ram graphics is also well 4000 in this laptop performance is very smooth the game is running is very smooth. Its a best option for its money.
