There was a comment on one of the mac forums about if you spend $3K - $4K on a MacPro three years ago you didn’t buy it to update your facebook status. Production systems are an long-term investment, especially for corporations. In the past was able to justify pushing a large monetary investment to a company for handful of systems that were supposed to have a production life of more than 3-4 years. While I love code that runs like it’s supposed to I don’t think Apple made this decision this for OS stability. Microsoft couldn’t do this because so many developers can operate outside their circle, when Balmer cried “upgrade (to Vista) or die!” no cage was rattled and I’m still seeing new systems deployed running XP in 2012. Apple is far more heavy handed when it comes to that. 10.7 development wont come to a crashing halt but fewer and fewer “legacy” Intel supported titles will ultimately be the result, especially with major enterprise titles: namely mac versionsof MSOutlook, MSOffice, and Adobe Creative Suite.
Hopefully I’m wrong but in the mean time the department of Mac Pro’s I support are viable candidates for Windows 8 now.
I’m not trying to sidetrack the post, so I’ll just say with the decision by Apple to take a fair number of Intel macs off the playing field will Daz develop for 10.6, 10.7 and 10.8 or put all their eggs in one 10.8 basket going forward (do lions even lay eggs?), if so how many Mac based studio/hex/bryce users are eligible for this upgrade and how many plan to do it? Granted, the upgrade could not be cheaper, it’s 1/10th of what Microsoft is asking for but Apple has a very different business model and can do things like that because of it.
