I think when comparing the two I5 models you are getting into the "splitting hairs" department. $300 to double both RAM and SSD is a good deal and well worth the investment, IMO, and therefore meets my personal "bang for the buck" threshold", plus giving you future proofing for both memory and storage. On this point, it's just a difference of opinion, with neither of us being wrong.
Yes, of course. I was only expressing my understanding of the offering. But I have no special insight...just an opinion...and not a very technically aware one at that.
