FYI Apple refurbs are 'better' than new.
They don't send out the same laptop with the same issue, hence the name 'refurb'.
When apple gets a return, they first replace the casing. Weather it was damaged or not. Each casing already has a new serial number. The insides of the old laptop (desktop etc) get installed into the new casing minus the defective part, that is replaced new. Each refurb is put together by hand, not a factory line.
Furthermore each refurb is tested and checked.
As opposed a new one coming off the line may or may not be checked. They ( new) are checked in "lots", for example 1 out of every 100.
A new laptop (desktop) is more likely to have issues than a refurb. Yes you heard that right.
So you can buy a refurb laptop (desktop) that has been put together by hand and tested and checked and save money or buy a laptop (desktop) that comes off the line and may or may not be checked and pay more money. Hmmmm. Hard decision.
Dont hesitate to buy refurb. It is better.
