Need advice buying laptop?

My choices are:

Lenovo ideapad Z460

DELL E6410

Toshiba Tecra M11

They all have same price range and same specs. I want to know which is better

Sony and Toshiba are good laptops. You might also consider Apple IPad as an option. Secondly, look at ram capacity, it comes in 32gig, 64gig, 128gig, 256gig, or more. Depends what you do with the computer, for just regular internet as and typing probably 32 or 64gig will do the job. If you are involved with gaming and graphics design you need 128gig or more for a better job. So you got to decide want you want to do with the computer.
