WARNING DO NOT BUY THESE.
These machines have a well known design defect where the keyboard fails. It was the subject of three class-action lawsuits and last week Apple announced a repair program.
HOWEVER: I am at the Apple Store now and they are REFUSING to fix my broken Woot-purchased, “Manufacturer-certified-refurbished” Macbook because supposedly it was sold “as-is” and is ineligible even for this defect repair program.
The keyboards on these machines WILL fail and you WILL be stuck with a thousand-dollar brick like me. Don’t buy!!
