- Snow leopard broke many drivers and apps, so no upgrade
- Lion dropped PPC support, obsoleting my apps, so no up-upgrqade
- Not interested in sandboxed apps
- Not interested in walled garden app store, or giving apple 30% to dumb down apps
- Not interested in "single screen" apps or other IOS-ery (IOS needs to move towards OSX, not the other way around)
- Leopard is very amenable to Hackintoshery, which I think I'm going to need (Macpros? When?)
- Leopard has actual install media... it's like XP, it will live for many, many years
- Leopard has everything I need -- seriously, there's no reason to go further at this time.
- Leopard is now seeing fixes from the community, since Apple hasn't fixed their bugs after 4 years (invalid console error messages from cron, anyone?)
- Virtualization means that I can provide a proper environment for Leopard over the forseeable future in non-native machines.
- No need to upgrade.
Apple *could* get me back. They'd have to produce a freaking awesome Macpro to replace my current one, which is still powerful enough for me today (8 cores, 3 ghz, 8 GB ram)... I'd be severely tempted by a four CPU, 24 core, 48 thread machine with lots of memory and PCI lanes/cards/capacity so I can continue enjoying my multiple display antics; and to this, they'd have to add a version of OSX with PPC emulation restored and under which a good number of the apps they broke began to work again. I don't expect any of that, but that's ok... HP makes some awesome hardware suitable for Hackintoshing. Leopard is a terrific OS with everything I love about the Mac pretty well nailed down. Beginning with Snow Leopard, OSX began moving in the wrong direction, and Lion... Lion is just a complete mess. Leopard supports 64-bit data models, that's the key tech that ensures the OS can handle big jobs. 64-bit program space isn't particularly significant.
The screwups with IOS5 don't exactly inspire confidence, either. The wifi sync works under XP, a 10 year old os, but not Leopard? Good job Apple, way to leave 20+% of your users and financial supporters in the cold while sucking up to windows. Not that it's worth much, considering you have to have iTunes on and the iPad plugged in to power for "wireless" sync to work -- lol. And then there are all the apps that crash or won't even start under IOS5, and the power problems, and the bookshelf taking up useless space, and the loss of the Kindle store link in the Kindle app... I don't think the Apple I see today is the Apple I bought my computer from, and that's not a good thing.
