Another, and potentially better deal is Best Buy today deal of the day on a MacBook Pro with the same price, and being new it has full Apple Warranty with Apple Care available for purchase.
Without the ability to upgrade the storage or RAM, Apples are not really worth it anymore.
I have two of these, with 512GB storage, just looking for a family member to donate them to as they are useless once your needs exceed there limits.
Can’t you use external drives for additional storage needs?
(Although I do agree with you regarding the lack of ability to upgrade the RAM.)
