I guess the M3 Pro is fine for what it is, a decent upgrade over the standard M3. However, my disappointment is what it APPARENTLY will do to the performance equation on the next Mac mini.
With the M2 Pro the Mac mini could have been considered as being at the low end of the "pro" experience for Apple silicon. But with the M3 Pro's restricted CPU and memory (only a 4GB increase in maximum RAM) I don't see how it can compare in any way to a Mac Studio with the M3 Max. I guess that could be one of the reasons why Apple made this change and it means that I am no longer considering an M3 Mac mini Pro for my desktop.
That said, might we see an iPad with the M3 Pro? Seems quite possible and that may be another reason for the de-spec on the M3 Pro. Seems like what they have done is to emphasize power efficiency and lower cost and that's exactly what they'd want for an iPad. Plus, it will probably improve margins on the Mac mini Pro or at least allow them to hold steady given the apparent price increases that TSMC has demanded for their advanced fabrication processes.
