I will say in all my years in professional development, I have only met one legitimate Mac fan boy and this was in the past three months. Maybe they're more prevalent on messageboards or hang out in the Apple store, but the stereotype (in my experience) is far different than the normal mac user.
The funny thing about this guy
Honestly
But this fear of lockdown? That's just traffic driving sensationalism. And if it isn't
This is not a sign of lockdown
This is a GOOD THING as now Mac's will have a better supported and up-to-date JVM and updates should come quick and fast compared to Apple's sluggish almost apathetic attitude towards releases.
The money they make in developer keys would be far offset from the money they would lose in hardware sales. Such a move would enrage their users, not to mention their own developers. All but the hardest of the hardcore would stay with them. No business in their right mind would use them. Apple has made some dumb choices in the past (headphone controls ipod, anyone?) but they aren't suicidal.
A few years ago when I worked at ESPN.com, the home page would start autoplaying a video with an ad before it hit Sportscenter. The higher ups loved it because it generated excellent ad revenue, but there was a near revolt in both the tech teams and editorial teams. They ultimately pulled it, looking for revenue elsewhere. I wouldn't be surprised if a similar revolt took place at Apple over locking down general purpose computers.
Many people write memos to tell you they have nothing to say.
