I am in the same boat. I don't need a laptop urgently, but would be willing to spend up to 1500 for the named configuration of 16/512g. As it is, the last Apple laptop I bought was the late 2008 Macbook. Which already had 4g of main memory for around 1200€.
There is also an elphant in the room: the keyboards. Until shown otherwise, I wouldn't trust their longlivity beyond the 4 years waranteed by Apple.
