It will not be "relatively easy" to keep a cars temperature at a set point. Cars have MASSIVE heat gain in the summer. Most cars have an AC system as large or larger than the one in your home. A car is pretty much a greenhouse on wheels.
Buddy, you hit the nail on the head. I manage a network of 20+ macs with 2 mac servers. I'm typing this on a mac. I say this to hopefully demonstrate that I'm not a troll or a windows fanboy.
Try maximizing a window on a mac. Minimize a window, then alt-tab back to that app. You get the app, with no window! You then get the 'pleasure' of moving the mouse to the menu bar, selecting the window menu, and hopefully finding the window you wanted.
On some Apple made apps closing the main windows does not close the app, on others (still made by apple) it does. System Preferences I'm looking at you here.
I Spend more time in my day fighting the mac interface than I do getting productive work done. Yes this is an exaggeration, but that is how it feels.
OSX server (both tiger and leopard) fail in such spectacular manners that it would make your head spin. The admin tools crash all the time. Open Directory loves to trash it's LDAP database. God help you if you need to restart your server after an update to iTunes! Make sure all your OD data is backed up somewhere right before the reboot. Oh, and be ready to do a repair on all the filemaker data while you are at it.
If you install FileMaker server on OSX Server it will overwrite your php.ini file with it's own idea of the settings you need. Among those, it reduces the php mem amount back to the default 16 megs. The bundled (by apple) web apps on the server can't run in that little memory. For those that don't know, FileMaker is owned by apple.
Seriously though, apple does make nice equipment. It just seems like they don't give a crap on certain issues.
