I was actually thinking more in terms of security and support.
PPC architectures are not very well supported nowadays, and haven't been for over 5 years. Perhaps longer. Sure, you can still run your machine on 10.5 and it might run really well still. That's no reason to trust it for mission critical tasks. God forbid if someone was using a OS X Server 10.5 and users trusted it with their credentials.
Vanity was pretty low on my list, but I understand everyone's priorities are different.
I was mocking the consumer perspective but obviously HN is too sensitive...
Not sure I trust Apple with longevity. Windows XP from 2002 just hit the dust and I've got a decade out of RHEL. For something from 2007 to be a write off is not good IMHO. I thoroughly regret my MBP purchase for theae reasons.
By the time Apple drops support for your hardware you have a decent chance of being able to install a current Linux distribution with no hiccups and full hardware support, so all is not completely lost.
Possibly right but I don't see how a piece of hardware that is pretty much glued together (as of recent MBA and MBPs) is going to survive that long to be honest.
Turns out if you missed the 10.5 -> 10.6 or 10.7 upgrades, you appear to be hosed unless you can find some physical media for those releases, you can't go 10.5 -> 10.8 (never tried ->10.9, would not expect it to work).
Apple still sells 10.6 (the physical DVD) online (at it's original price, $20) for anyone still stuck on 10.5.
Once you're at 10.6.8, the Mac App Store is available for further upgrades
That's true. The latest OSX releases won't install on some of the early Intel Macs. I've heard it's possible, with a certain amount of hacking, to get an early Intel MacPro for example to run 10.8 or maybe even 10.9 but it's unsupported.
