apple servers
why?
Let's take a look at the server market.
Linux, stable, cheap, efficient with widespread industry adoption.
Windows, less stable, not so cheap, bloated, ineffecient, better integration between servers and desktop machines and an abundance of cheap MCSE's are it's only selling point.
Solaris, bombproof, expensive, shiny hardware, proper support channels to keep the PHB happy. (HP/IBM unix is the same sans the funky hardware)
OSX server, Shiny hardware (I assume, it is apple after all), expensive, glossy gui (bloat), virtually no industry adoption and questionable support channels. Also, what native server apps can you get, or is it just ports of Apache, MySQL and sendmail?
If you want shiny servers in your racks and have wads of cash then you would be better off getting a real server from Sun.
If you want to run cheap, reliable servers, buy some boxes off IBM/HP/Dell and run Linux.
I can also see a case for running 'doze and exchange for AD integration between servers and clients, although I wouldn't do it myself.
But apple and OSX? I just don't get it.
