I think it is really a very simple question: do you want to run the software you have now, at the fastest speed possible, with all the current defects? If so, get an Intel machine now. If you want to be able to do future, different things, wait for the ARM machine.
Personally I would use something like an Apple Chromebook. Long long battery life, more secure (from hardware support like the trusted enclave, microarch stuff like tagged pointers, and the OS moving towards unpriviledged applications and code signing), better iOS integration.
I think we're actually overdue for Apple to offer cloud offload processing, especially for iOS, but maybe offload to the edge (your macbook) becomes easier with ARM.
