I bought this device in excellent like new condition as an open box at an Apple authorized retailer. It was considered over the 60 days. The device was purchased in August of 2019. Due to the large amount of Apple devices I have they said they would make an exception and let me purchase it if I want for a one time purchase of $379. Is it worth it? This machine also has an i9 and 512gb of ssd so I intend to probably keep it for awhile. Other than the potential keyboard issues are there any other issues I need to be worried about?
