I guess you are the only person in the world who thinks it is better to be slower by having to wait for applications to reload, rather than having sufficient RAM so that this doesn’t happen.
I have never really had that problem that I've noticed, and I suspect most users are in the same boat. It all depends on the use case, and I suspect Apple decided 8 is enough given the OS's memory management. My previous MBP (2018) had 16 and my M1 Air 8 and I've not noticed any difference in applications.
If RAM is insufficient, the iPad Pro cannot hold all applications in memory. Which is what is happening with 8 GB of RAM.
This isn’t rocket science is it?
Are you also going to dispute that a 500ml glass is insufficient to pour 1 litre of milk into it?
No, but it is if all you want is 500ml. Going to 16 would add cost to the device without noticeably improving the experience for most users, so it makes no economic sense to do that until it is needed to maintain the experience for 90+% of the users.
The money could be better spent making the iPad more of a portable replacement for a Mac.
If you pour half of it, drink it, then pour the other half; yes, that's a lot like what I said.
Exactly.
