Seriously. Programmers making >> $100k hem and haw about upgrading a tool they use 10 hours a day. It's worth it to upgrade for $100 even if you use it for a week, let alone 6 months.
That seems optimistic, the M1s were already discounted $65-150 earlier this month. I think the decider here would be simply having an M1 if your workloads benefit from it.
If you can’t wait, this is sound advice. However, if you can, it’s likely worth it, on this rare occasion.
