Which is the best laptop for programming Linux

Hi I know that this is not the right place to ask the question below but still I am asking because only the Linux professionals like you can suggest the right.

As I am bored with the behavior of the present laptop I want to buy a new laptop.

The issues I faced previously are below

Also the system crashes frequently.

As I want to learn linux programming I want a laptop which provide best performance and highly compatible with Linux.

As I don't want to watch movies or something else so can you suggest which is light weight, less in screen size and cheapest.
