People are missing the point about the integrated graphics. For me this is a feature not a bug because it has USB-C instead. That means that instead of hopelessly compromising thermals and power supply with some power hungry, yet limited GPU (because of the small form factor) you simply buy the CPU and memory that you need. It simplifies the job of keeping it cool. CPUs are evolving a lot slower these days. This one…
It's not so much that I want a gigantic GPU, but I'd like something that could just run two external 4K monitors without stuttering. That would make this an excellent general-purpose desktop machine. The 15" 2017 MacBook Pro does this fine, so it's hard to accept that it would be difficult to engineer something into place. Unfortunately, an eGPU is gigantic external box costing a large chunk of change, so it's not re…
Besides, with Apple you are paying a premium for a dedicated GPU in a macbook, which makes the price of an external eGPU less of an issue. Because if the choice becomes paying 500 euro extra for a mac mini with a last generation laptop grade GPU or spending the same on a eGPU with modest specs (or a bit more on something fancier), that's a lot easier to defend. Especially if you can swap it out once every other year for a new one.
I'm guessing that with the mac pro they may offer some options for a dedicated, non upgradable GPU as well as eGPU options. Most professionals would probably prefer investing in the latter because it provides them performance without much compromise and an easy way to upgrade. E.g. I'm still waiting for Apple to make a move with AR/VR, which they sort of support but which they don't really actively promote currently.
Anyway, the mac mini is not necessarily that interesting for people looking for cheap options. The start configurations are nice if you don't need much but most more serious users are going to want bigger ssds, more cpu, and more memory. That creeps into the mac pro use case already. I'm guessing that in terms of price segment this thing is designed to fill the gap with the mac pro, which will likely have a starting price of around 5K, just like the last one.
