(1) I just noticed this deal going on - https://www.apple.com/shop/refurbished/clearance But there are two sections - one is refurbished, and the other is clearance. I am not sure as to the difference between the two. I see that there are no SEs in the refurbished section, and no iPhone 7s in the Clearance section. (2) Does it make sense to get the SE now? For how many more years is it likely to be supported with updates?
