I've been through enough Mac upgrades by now to learn that I'm going to have a better time waiting for M2. I'm not really interested in jumping on this particular early adopter train. As a developer, who knows what random tweaks and system behaviors I rely on to get my job done, but that will be completely broken on a new Mac.

I certainly am heartened by all the news about processing power improvements. I'll just join the rest of y'all young whippersnappers after you pay the early adopter tax for me.
