Which computer would you never suggest to anyone?

For me it's DELL.

I say that because they have a pathetic policy when it comes to faulty parts. They will replace your faulty part with a refurbished part. It won't be new. It will probably be a part from another faulty laptop.

In the span of 3 years, I've got my 3 HDD's, 6 LCD's and 2 adaptor bricks replaced under warranty with refurbished parts.
