Apple have such a colourful history of user evangelism and unwavering loyalty from both the end-users and third party developers because people have truly believed in the platform beyond the usual monetary reasons. People like these guys are proof that the support given to the Mac platform is unlike any other.
The very idea of having just a handful of PowerPC Power Macs IN EXISTENCE at the time of developing Graphing Calculator makes it such an appealing concept to be working on a platform which was truly leading edge. This is something totally lacking in the current lineup and in my opinion, has been this way since about 2008. I would welcome something like an architecture shift as we discussed in the other threads simply for the sake of shaking the Mac up and making the platform something appealing with unique capabilities (again).
Back when we (the Mac advocate) brought Apple out of the darkness and from the brink of failure, around the time of the iMac, we wanted everyone to buy a Mac, to support our favourite brand and preferred computing platform. It wasn't uncommon for the average Mac user to do the sales work and convince their family and friends to buy a Mac too.
It's a shame the Macintosh platform has fallen so much to the wayside and now simply sits in the shadows of the iDevice successes. There really is very little which makes the modern Mac stand out, other than being an Apple branded accessory to the typical consumer market user who already owns an iPhone or iPad.
What are the chances of getting away with slipping your software into the distribution GM under the radar like that? And then retroactively licensing it out to a userbase of millions.... what a time to get involved.
