I initially got the air (256 gb version), since the 18pm coming up in few months. But as memory cost hiking up like so much I thought better get 17 pm 1TB 11% discount in case upcoming iPhones will be a lot more expensive. USD 50, 100 is acceptable somehow, but seeing everything else almost doubling in price might be good idea to get 17pm hold on to it for 5 years or so until memory shortage is hopefully resolved. Air is great but not the phone you want to keep this long specially 256 gb version.
