PythonWallace: Ever heard of appleTV ?? LOL, I'll be honest I'm not THAT into apple products that I even know all the features of it. The macbook pro is the only apple product I use. Personally I would be in the same boat as you, I would rather have the flexibility of open source software for my media library. There are probably such applications for macs but unless your using their media appliance I don't see to many people being able to afford a "spare" mac and using it for media storage and delivery LOL -Just another personal preference having worked in networking as one of my many duties over the years I would still use good 'ole ethernet for anything delivering alot of data...especially media files.
Brimstone: Your point is well made...in your situation. What something is "worth" and how it applies to other situations varies infinitely. Being able to run OSX and Vista side by side couldn't be more perfect for me and my job. I need to be able access tools to support both mac and PC users on a daily basis. Before I got approval for the purchase of the macbook pro I run now I was always scratching my head for a good 5 minutes or more just trying to figure out or remember where something was in OSX. Now that I operate virtually simultaneously in both operating environments I am MUCH more efficient at addressing my user's issues. Granted you need to have a machine that can handle the work load and in my case I am very happy with the stability. When OSX is able to run on PC's/windows legally and without hacked up versions of OSX it will only make sense to revert back to the cheaper, more easily upgradeable hardware.
I'll say again...I'm no fanboi of either "side" I look at being able to efficiently use multiple operating systems as valuable skill in my career. In technology you don't gain employment by convincing someone that what you know is "better". You definitely increase your chances of employment by being flexible and diverse
Even though this has gone WAY beyond what my original post was about...I think we all have our preferences and everyone's technological needs will vary and there are numerous options out there to fulfill them.
