Just curious, you and a couple other posters have said you expect Apple to upgrade the internals more often now. What is that thinking based on? They do not seem to regularly update the Mini and they have a whole line to upgrade with Apple silicon now - MacBook pro, iMac, mac pro...I expect the MacBook pro will get an upgraded M1 at some point and I could be jealous for years before I see it make its way to the mini.
"IF" Apple starts to release products faster, there are two motivators, and it is not 'as the tech becomes available;' all of the tech has been there since November.
1. As leaked by one of their hardware engineers that went to Micron, there were several versions of the M1 ready for integration, but marketing put the brakes on any wide release. With such a small market segment, Apple has decided to stay with the high cost of entry, and the "What's Next" hook'em mentality. A more frequent release cycle will come because the tech is there, and it is on someone's project plan with an existing release date.
2. An attempt to hold their place in the computer race with strong up and comers like Huawei, Chuwi, Xiaomi, and (yes) Lenovo (also a Chinese owned company, once known as IBM). Specific to the iPad competitors, I'm under an NDA, but if a product currently attempting to get a patent is successful, they already have manufacturing ready to be in production within 4 months, and are sitting on parts inventory in India, this is going to shock Apple. Now that we have a President that does not care about who does what to whom, when or where, I don't think India is going to have any problems importing it, and doing so at half the initial retail as Apple, or Samsung for that matter.
Releasing on a more aggressive timeline goes against Apple's MO, cramps their artistic style, and subverts their pricing model justification. When the next release of M_ chip variants hits, it is going to fill three missing segments; higher end laptops, the all-in-one's, and the pro line. Apple is going to leave the entry Mac Mini alone. The iPad's will get an updated CPU, but it won't be in the M-genome, but another iteration of the A-line.
My ever increasing gut tells me they are going to spend some capital on the top end of their product offerings, and finally give some love to the actual productivity pros.
