However, seeing that the nTB 13"MBP with 7th gen intel and 64MB eDRAM starts at $1700 (16/256) and the TB 8th gen version (with 128MB eDRAM) starts at $2000, I can't see a Mini based on the MBP 13" innards starting under $1000.
This is what's so frustrating about Apple's recent business model. In the past I would buy a Macbook Pro/iMac/iBook etc with a relatively modest spec, and then upgrade it a few years later to give it some extra life. It was the equivalent of spreading the cost. Now they force you to spend $2000+ up front. I understand why they are doing it, so they get that money rather than a third party part supplier, but what they seem to have forgotten is that a lot of people can't afford or don't want to buy a $2000 computer from the get-go.
