This has nothing to do with Dell. Dell made the computer and put Sony batteries in them, the same as Apple. Both recalled them.
Dell's not the largest computer company in the world because they have crappy computers. They sell $54,000,000 a day! They are computer suppliers to over 80% of the fortune 500 companies in the world.
Not to mention, Dell owns Alienware too. They are now going to AMD as well....who could honestly ask for any more than that?
